Import all translatable texts from core Gutenberg library

Problem/Motivation

Gutenberg uses this file https://git.drupalcode.org/project/gutenberg/-/blob/3.0.x/js/drupal-gute... to handle translatable texts.
The problem is that pretty much all translatable texts in the core library aren't in this file.

Proposed resolution

Create a script to go through all core library files, fetch translatable texts and add them to the JS file so Drupal can discover them.
