Drupal 11 compatability

Hi @imclean,

I have resolved the pending issue for Drupal 11 and created Merge Request MR! 3.
Please review and verify.
Thank!

Thanks @sarwan_verma. Will the module still work with versions of Drupal prior to 10.3 after this change? See the change record → for more information.

Would it be possible to tag a 2.2.6 or 2.3.0 release with Drupal 11 compatibility?

I'd like to soon but I'm not sure the change proposed in the merge doesn't break compatibility with older Drupal versions.

@sarwan_verma can you review the change record I linked to.

I just checked and the deprecated method will be removed in Drupal 12, not 11. I'll tag a Drupal 11 release and this can be fixed later.

@sarwan_verma this module supports Drupal versions from 8.8 onwards. At the very least I'd like to support 9 and 10 as well as 11. This requires using the DeprecationHelper to maintain backward compatibility. This is described in the change record I linked to in #6.
