Description

Renamed the various docker compose files to be prefixed with docker-compose. and updated references.

Checklist:

• I've made sure that tests are updated accordingly (especially if adding or updating a template option)
• I've updated the documentation or confirm that my change doesn't require any updates

Rationale

Fixes #4983 (makes the files' purpose clear, puts them next to each other alphabetically and therefore visually in most editors, and lets VSCode detect them as compose configs)
