Backend: Create project template for CI components

Problem

As a user wanting to convert some existing CI templates to components, I would like to quickly spin up a new project and not have to read the documentation on what steps to follow.

Proposal

(merged with #435035 (closed))

To simplify the process and to ensure users follow the correct workflow, we could create a project template available in https://gitlab.com/projects/new#create_from_template for a catalog resource hosting CI components:

• README.md filled with a template of information to fill in.
• Example of .gitlab-ci.yml with how to test and release components.
• Example of templates/component.yml file to edit.
• LICENSE file
• .gitignore

This task has been started, please see related merge requests below for the two draft MRs.
