Replace non-test usages of \Drupal::languageManager() with IoC injection

We do this for non-test code under this issue.

Per the parent issue, rescoping this to do it for non-test code.

So i have to set this back to NW, sorry for the change in the middle!

I do not think we need a new trait here. ContainerInjectionInterface might help. Tests did not pass.

@ankitsingh0188 thanks for working on this.

See https://stackoverflow.com/questions/18142870/git-error-fatal-corrupt-pat... for the error, maybe you should try the git CLI to get the patch or see https://www.drupal.org/docs/develop/git/using-git-to-contribute-to-drupa...

Also, please see #3123210: Replace non-test usages of \Drupal::theme() with IoC injection as a good example.

Those are not "Using IoC as possible". They are almost the same. Again see fixed issue #3123210: Replace non-test usages of \Drupal::theme() with IoC injection as the example.

The patch is fine now, but the patch itself did not address this issue. Please see the one I linked in #21 as an example, or read the parent issue.

Or see the commit of the issue #3123210: Replace non-test usages of \Drupal::theme() with IoC injection as the example

>I think the patch #25 will address the issue as mentioned in #21

Nope, see #26

This is fine. it's constructor property promotion introduced in PHP8, let's adopt it in this issue. and hopefully, it gets applied to other sister issues.

A change record link is expected. Tagging needs CR.

Hi, @ankitsingh0188. I will work on this.

Unassign myself, #37 may be good for review.
