Update for Drupal 10

Created an issue fork, cloning to my development machine to try updating the code.

First error, as expected:

The website encountered an unexpected error. Try again later.

Drupal\Core\Extension\InfoParserException: The 'core_version_requirement' key must be present in modules/rsvplist-3449703/rsvplist.info.yml in Drupal\Core\Extension\InfoParserDynamic->parse() (line 67 of core/lib/Drupal/Core/Extension/InfoParserDynamic.php).

Module installed and configured fine after adjusting `rsvplist.info.yml` to core_version_requirement: ^10.

Not surprised the next issue shows up when testing the RSVP Form on submit. Firing up Xdebug:

The website encountered an unexpected error. Try again later.

After updating the submitForm() function to be compatible with Drupal 10, the next issue is at /admin/reports/rsvplist:

The changes I made were the minimum possible to support Drupal 10.

Hi @alexb7217,

I enabled the RSVP List module against 1.0.x-dev on my Drupal 10 site, tested all the functionalities, and confirmed it works without getting any of the errors mentioned above.

Please see the attachments for reference.

I'm marking this now to 'RTBC'.

Thank you.

Fixed.
