Remove the drupal/core requirement

Maybe I thought it was necessary due to the module's removal from core and that's why I left it in. But it never should have been necessary as long as the core version requirement in the info.yml file required D10.

@larowlan any thoughts? This was prompted by the D11 update issue that's still trying to increase the core version constraint in the composer.json file.

Yep, let's ship it, cutting another release
