`v1-beta` release does not work with git short commits with a different length than 7 chars

Depends on: #123

As we described here that release does not work of git commit return a hash with not exactly 7 characters.

You can fix the problem by forcing git to use always 7 characters for short hashes:

- name: Set the length for git short commit hashes
  run: |
    git config --global core.abbrev 7

Adding that step before using git-queue. As we want to stop using short commit hashes I think we can fix it by releasing a v2-beta version once #123 is finished.

I have just updated this release v1-beta to fix that bug.
