Create Custom Permissions 8.x-2.2 release for Drupal 11 support

I've been reviewing and testing various issues and am waiting on a couple to be tested by others (the first one is most pressing):

🐛 Permissions that depend on disabled modules prevent any editing/creation of other permissions Needs review
🐛 Module does not work with routes that implement _entity_access Needs review

No one has reviewed the issues noted in #2 so I'm going to move ahead with the release so at least there's a D11-compatible release.

Issues included:

📌 Automated Drupal 11 compatibility fixes for config_perms Needs review
📌 Replace README.txt with README.md RTBC
💬 Deprecated function: str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated in config_perms_parse_path() (line 41 of modules/contrib/config_perms/config_perms.module). Active

Whoops. Made a mistake with 8.x-2.2, so tagged 8.x-2.3:
