erlang@27, or simply erlang, is already out for Homebrew. I'm not sure if that's what's causing the CI issue.

It's been hard-coded, we should be able to remove that @26 and let the macos tests pass now https://github.com/erlang/rebar3/blob/29ccddb72284eb61701b1945699edbdf484a8f2d/.github/workflows/main.yml#L56-L57

This is very useful info. I suppose it will be also nice to have some command in rebar for print supported versions.

If this is ever considered we could then use it in the generation of the README to avoid two sources of truth.
