Add Drupal 11 support

I can not fork this project, so here is a patch for Drupal 11 support.

The patch updates the core_version_requirement in domain_microsite.info.yml to include Drupal 11.

To apply the patch:
1. Download the attached patch file
2. Apply it using: `git apply domain_microsite-drupal11.patch`

The changes are minimal and only affect the info.yml file to add Drupal 11 compatibility.
