chore: Fix build warnings

Although we are not building anything new with `gen_queue`, it is still worth
fixing some minor issues.

1. Switch from Travis to GHA.
2. Change `@since …` attributes to `@doc since: …`.
3. Run `mix format`.
4. Make Elixir 1.15 the minimum version supported.
5. Fix a badly named test file.
