📖 [Docs]: README pages now use the standard module landing-page format

[Marius Storhaug (MariusStorhaug)]

The Jwt README is now a concise landing page. Users get a short overview, one-line install, a
copy-paste Usage showcase using the real commands, and links to the published docs — instead of an
exhaustive command inventory that duplicated generated help.

What changed

• Usage showcase — realistic examples for New-Jwt → Test-Jwt → Get-JwtPayload (create an
  HS256 token, validate it, decode the payload).
• Security note — a caution that the none algorithm produces an unsigned token and should not be
  used for authentication or authorization.
• Documentation — points to psmodule.io/Jwt plus a real discovery
  snippet (Get-Command -Module Jwt, Get-Help -Name New-Jwt -Examples).
• Removed the redundant ## Commands inventory (duplicated generated help) and the
  ## Contributing section.

Technical details

• Updates README.md only.
• Aligns the README with the PSModule module landing-page standard.
