New Content: docker-compose clarification

[maxibenner]

Is there a topic or section missing from the docs? Please describe.
The section on docker-compose could use a few more details. I'd be happy to make a PR if everyone agrees that this would be useful.

Describe the content you'd like to see added:
I'd add a section (maybe a callout) that notes the following:

1. Which configuration doesn't need to be added because coolify adds it automatically e.g. volumes, container_name, restart.
2. That images should be pinned to a particular version (as opposed to latest) to prevent the template from breaking due to upstream changes.

Why is this content important?
I've noticed that there are certain recurring change requests for the docker-compose files when people create PRs for new services. I think mentioning those could save maintainers time by not having to repeatedly making those change requests.

Additional context
See this PR and my own PR as examples of these common issues.

Yes thanks, a PR would make sense.
