Add Drupal 10 Compatiblity

Please review. Made it Drupal 10 compatible and also it's dependencies are Drupal 10 compatible.

Awesome I had tested but as I am using it as a composer dependency there are a few issues on the composer.json, I removed the core requirement which is no longer required. ( https://www.drupal.org/node/2514612#core-compatibility → ). Also there is an error on the composer.json file which prevents to make the proper requirement of this module. On the "require part"

 "require": {
        "drupal/core": "^8.8 || ^9",
        "drupal/hook_post_action": "^1",
        "drupal/redirect": "^1'"
   },

The "drupal/redirect": "^1'" has an extra character. I had removed it from the fork and seems the composer let me install it but still showing the error I think because the main branch still has it.

"Skipped branch 1.0.x, Could not parse version constraint ^1': Invalid version string "^1'""

I will test more in a few.

I ran some tests more, seems everything is working :).
