Support D10

Patch contains recommended changes from upgrade_status,

New patch also removes D8 core_requirements

I have verified #3 patch working fine and applied cleanly. It resolves all the issues mentioned in the Drupal upgrade status module. Attached a screenshot of the upgrade status report before and after applying the patch.

One more question @Nels.
is it necessary to remove Drupal 8 version from 'core_version_requirement'?
else we can include in this way. Please confirm.

core_version_requirement: ^8.8 || ^9 || ^10

Updated patch to include jQuery.once deprecation.

@noorulshameera, I believe we need to remove the D8 support due to the change from Drupal\Component\Utility\Unicode to Drupal\Component\Mime\MimeHeaderEncoder.

wrong file name on previous patch, plus did not apply

This patch applied for me.

Thank you for your work and testing.

I added core/once as a library dependency and increased the library version.

Removed Unicode::mimeHeaderEncode part - not needed.

Removed D8 support.

Automatically closed - issue fixed for 2 weeks with no activity.
