Convert documentation examples into test module

Problem/Motivation

Create a test module to provide the examples of:
- https://git.drupalcode.org/project/ui_suite_bootstrap/-/blob/5.1.x/docs/...
- https://git.drupalcode.org/project/ui_suite_bootstrap/-/blob/5.1.x/docs/...

directly accessible in multiples paths for easier testing and evaluation.
