feat(i18n): add Dutch nl-NL translations

[WilcoSp]

📚 Description

Adding Dutch translations to npmx, I've also added nl as a language that has variants because of Flemish.

🧭 Context

This pr adds Dutch to the available languages, in case of "you" I've chosen for the formal variant ("u") instead of informal "je/jij"

terms usage (🇬🇧 = 🇳🇱)

• package = pakket
• dependency = dependency (stays same)
• provenance = herkomst verificatie / herkomst gegevens
• readme = readme (stays same)
• deprecated = afgeraden ('not recommended' in Dutch)
• like = vind leuk
• unlike = vind niet leuk
• contributor = bijdrager
• facet = Aspect
• playground = playground (stay same)
• issue = issue (stays same)
• patch = patch (stays same)
• minor = sub (semver)
• major = hoofd (semver)
• operation = opdracht
• command palette = actie menu (action menu, describes closer what it does and makes the placeholder translation possible, 'snelmenu' (quickmenu) was also an option but the placeholder couldn't be translated than)
• command (only in command palette) = actie
• home/homepage = start/startpagina
• freshness = recentheid (for compare)
• cookie = cookie (stays same, unless talking about an actual 🍪)

Translations that stay the same because these are already used by Dutch developers as is and because the direct translations don't fit the context of npmx & developing software.

🤖 AI & translator use

I did use Chatgpt, Gemini & Deepl to assist translating while going over each page & translation individually to get the best translations

What's the progress on this? No pressure, just curious!

I'm still translating and getting further and further but my time is split between this pr, #1233, work and personal life.

I'll add an overview at the pr description to get a better indication how far the translations are

just temporarily disabled the "Allow edits and access to secrets by maintainers ", this is mostly due to autofix bot which when sync back can cause merge conflicts. When open for review it'll be enabled again.

No worries! If it helps we can always merge this partially translated, and then you (and/or others) can contribute more in follow up PRs - but it's up to you!

📝 Walkthrough

Walkthrough

Added Dutch language support by registering a base nl locale and Netherlands variant in config/i18n.ts, and adding two new locale files (i18n/locales/nl.json and i18n/locales/nl-NL.json) containing Dutch translations and region-specific overrides.

Changes

Cohort / File(s)	Summary
Localisation Configuration config/i18n.ts	Registered nl as a base locale and added nl → nl-NL mapping to countryLocaleVariants; enabled the active nl locale entry (previously commented).
Dutch Locale Files i18n/locales/nl.json, i18n/locales/nl-NL.json	Added comprehensive Dutch translations (nl.json, ~1552 lines) and a small Netherlands-specific override file (nl-NL.json) with keys such as auth.modal.handle_placeholder.

@ghostdevv I've just translated the last things I think should be translated for this pr.
the only things I haven't translated are the privacy_policy, vacations & compare.scatter_chart.

• for privacy policy the time will need to be taken to translate it so probably best for a different pr
• vacation doesn't have any priority rn
• compare.quadrant_chart or now compare.scatter_chart still very new and will probably still change a lot

In `@i18n/locales/nl.json`:
- Line 365: The "not_found_message" translation contains a typo ("nit"); update
its value to correct Dutch ("Dit pakket kon niet gevonden worden.") and scan the
other high-visibility keys referenced in the comment (the other locale entries
at the given positions) for similar misspellings—replace "nit" with "niet" and
fix any other spelling/wording mistakes found so that all user-facing strings
read correctly in Dutch.
- Line 1133: The localization key "view_profile" in nl.json uses the Dutch token
"{naam}" which doesn't match the expected interpolation token "{name}" used by
callers; update the value for "view_profile" to use "{name}" so runtime
interpolation works (locate the "view_profile" entry and replace "{naam}" with
"{name}").

what's this? 👀

[WilcoSp]

Alice isn't a common name here in the Netherlands so I changed it to the national color 🟧 instead to be more recognisable

[ghostdevv]

ah, awesome!
