Overview of changes:
#2882
Replace error logging with silent skip if page does not exist when serving one-page.

Anything you'd like to highlight/discuss:

There should no longer be any pagefind related indexing errors when serving one-page.

This issue arose from #2880, where I began switching the searchable page logic to respect page's option. It was an oversight an oversight by me during development as I had only tested the indexing with a full build. However, using markbind serve -o only the landing page is built at startup. The sitePages.pages array contains all pages defined in site.json, but most of their HTML files haven't been generated yet as they are built on-demand when u navigate to them.

As prof @damithc mentioned,

In fact it is because these pages don't exist when using -o flag. I think we should not show those as errors in the console, as missing pages is expected when using -o mode.

Hence, I added a check if a file exist first. If it doesn't & is serving one-page, silently skip to the next file to index. This ensures that the failed to index error doesn't occur because the file did not exist.

This is 100% my bad and on me, my apologies for not realising this earlier. Will be sure to be more thorough when testing out newly added/updated features in the future.

no worries @MoshiMoshiMochi , it is but a edge case that is not breaking 😄

Speedy quick fix!

if anything, these nits should be caught by the PR reviewer as well 😅

It could also mean our testcases are not comprehensive enough, to which we can improve on!

[MoshiMoshiMochi]

As discussed, I've update enabling pagefind to its' own option where it is disabled by default. Users will now what to enable it within by declaring the pagefind configuration and setting enablePagefind to true

{
"pagefind": {
"enablePagefind": true
}
}

Hence, as it is no longer tied to enableSearch which is true by default, all functional tests no longer captures pagefind.
