Fix more var and param docs identified by phpstan

Added a few more

Seems pretty straight forward

Checked an older pipeline from the parent issue https://git.drupalcode.org/issue/drupal-3404246/-/jobs/2138635 and see the issues mentioned.

I don't necessarily agree that this needs a follow up, it's more that a random issue was identified in the course of working on this issue, and it would be a good thing to do to create the follow up.

So here it is 📌 Remove $message param from \Drupal\Tests\comment\Functional\CommentTestBase::setCommentSettings Active .

Good point and I will choose my words more carefully next time.

Left some comments on the MR

Rebased and addressed feedback. Let's see if tests pass using empty strings where we had NULLs. It might be better to put the machine name as the label, or a human readable name, but it doesn't seem like the label is useful for these tests.

Sorry for the noise of assigning/un-assigning accidentally clicked the button. Cleaned up the threads some.

Believe feedback from @larowlan has been addressed
