GHA: enable running multiple try builds at the same time

While for auto, try and PR builds we only want the latest commit to be tested, that's not true for try builds: each commit pushed to the branch is a different PR being tested, and we want multiple PRs to be tested in parallel if there is enough demand.

Fixes rust-lang#70569
