PHPORM-146: Add override attribute everywhere

[paulinevos]

Closes PHPORM-146

Adds the override attribute in every class that extends a Laravel base class, so that PHP will show errors if ever the base methods are renamed or removed.

Also adds in a few corrections to phpdoc declarations where necessary.

Checklist

• Add tests and ensure they pass (not applicable)

Apparently git commit -m does not like backticks... will rectify commit messages I guess.

This is huge, and will be very helpful to detect when a parent method is removed.
I spotted some tiny changes.

We squash-merge. So you can refine the commit message in the merge box in GitHub.

Would it make sense to enable the checkMissingOverrideMethodAttribute config setting in PHPStan? That would help us keep the list up-to-date 🤔

Some methods are added in newer versions of Laravel, and are not available in Laravel 9, 10 or 11.0.
I don't think there is any method that has been removed. We could add this restriction only when phpstan run with the latest Laravel version.

Is there a way we can actually do that? I can only find a parameter for the PHP version in the phpstan docs, but nothing about a specific version of a dependency/Laravel in either the phpstan or larastan docs
