Fix incorrect type hint and make daily "updated deps" QA jobs pass

Technically there's no need to bump the version of drupal/coder in any composer-file.
Unsure if we still want to do this in this issue.

I don't see the need to bump Coder if we are going to fix the source of the issue instead. Added an updated deps test run to check that the fix works, assuming it does this is RTBC.

Well, if that's a const, I guess it cannot be a @var. Remove that annotation altogether?

@mondrake Per the official documentation it is allowed:

@var

You may use the @var tag to document the Type of the following Structural Elements:

Constants, both class and global scope
Properties
Variables, both global and local scope

https://docs.phpdoc.org/3.0/guide/references/phpdoc/tags/var.html

I see... Never seen that used in Drupal tho. Drupal's coding standards → don't mention anything. But they're outdated, anyway, do not mention visibility either. So :shrug:

The constant could be refactored away, ::class doesn't care if the class doesn't exist and it will evaluate to a string anyway, but that can be done in another issue: https://3v4l.org/0kGMp

Committed and pushed to 10.1.x and 10.0.x, thanks!
