Example setup for GitLab CI using prebuilt Docker image

[steveyyyy]

Hi,

I created a prebuilt Docker image for running moodle-plugin-ci in GitLab CI/CD.

It includes:

• PHP 8.1–8.4 (for now)
• Node.js 22
• Composer
• MariaDB & PostgreSQL clients
• moodle-plugin-ci v4.5.9

Repository:
https://github.com/ffhs/moodle-lms-plugin-ci
Docker:
https://hub.docker.com/r/ffhs/moodle-lms-plugin-ci

This could help with issue #39 and #223 .
It may be useful for users running Moodle plugin tests in GitLab CI or locally. There is also an example in the repo.

Best regards
