Issue #3450001: Add Drupal 11 support to core_version_requirement/composer.json

Jonathan Sacksickrequested to merge
issue/acumatica-3450001:3450001-d11-support into 1.x

Widen core_version_requirement (both acumatica.info.yml and acumatica_kit.info.yml) and composer.json's drupal/core constraint to allow ^11, alongside the existing ^9/^10 support.

Also drop the unused symfony/property-access requirement - grepped the whole codebase and confirmed nothing references PropertyAccess in any form, so it's dead weight rather than something needing a version bump for D11.

Closes #3450001
