Drupal core version support - update

[finnlewis]

We're still flagging Drupal 9.x support.

Current Drupal core support is 10.3 and 11.

See

• https://endoflife.date/drupal
• https://www.drupal.org/about/core/policies/core-release-cycles/schedule

We probably want to declare support for 10.4+ at this point.
