CI: branch named "tags" conflicts with magic "tags" keyword in "only:" entry

These docs tell me I can do:

only:
  - tags

Which means "run this job only when there is a git tag". I use such a pattern for my releases.

However I also seems you can use branch names:

  only:
    - main
    - tags

which I want to mean "only git tags of the main branch".

But what if the branch name is tags? In fact, I've just submitted a branch named tags... which then undesirably ran my release jobs.

Suggested tags: "section:ci"
