[pp-1] Address t() in new hook classes so they use StringTranslationTrait

Problem/Motivation

Postponed on 📌 Convert to OOP Hooks Active

Once that is in we can address all of the t() calls in hook classes and use the String Translation Trait.

Steps to reproduce

Remove `DrupalPractice.Objects.GlobalFunction.GlobalFunction` ignore rule in phpcs.xml
Run code sniff

Proposed resolution

Add the following:
use Drupal\Core\StringTranslation\StringTranslationTrait;
use StringTranslationTrait;
Convert t() to $this->t()

Remaining tasks

Change Hook.php classes
