Drupal 11 compatibility fixes for maestro

I should have pushed my D11 info.yml compatibility a while ago -- apologies for that. I pushed those simple yml file changes for now.

The linted output makes it difficult for me to determine what we're pushing into the repository.

I'll have to dedicate more time to look at the linted output as I see some changes to method/function declarations for nullable types. Perhaps just better shorthand for PHP 7.1+ -- just like some of the replaced is_set(..) with ?? operator.

Or we close this ticket down for d11 compatibility and open a new ticket where we can work through linting and code standard updates sequentially.

Going through all the phpcs and phpstan warnings... 😅

May be we should create a new 4.x dev branch for Drupal 10+ and PHP 8+?

MR pipeline results are getting greener :)

All green now, the unit tests are finally passing after a huge work on the schema file. Yay! 🎉
