Use non-tagged version of forc in CI

[Salka1988]

• the issue(s) this PR closes: fuel core 0.13 upgrade #657

added flags FORC_PATCH_BRANCH and FORC_PATCH_REVISION in CI
flag FORC_PATCH_BRANCH allows CI to use the forc version found on the given branch
flag FORC_PATCH_REVISION allows CI to use a forc version that is behind an existing rev. number

I understand the code and think it looks godd! I'm just not sure how we would use it in reality. Can you provide more explanation?

If I understood correctly, we need the option to use the forc version that has not yet been released and is located somewhere on a branch or under a revision number. If the assumption is correct, then we will do it like this:

FORC_PATCH_BRANCH = "Salka1988/new_unreleased_forc_on_some_branch"

This will install version from the branch and use it in CI. Same with revision number.

Makes sense to me. I've never needed to use an unreleased force version in the CI, but if that's a real need, then adding the option to support this doesn't hurt.

Did not demand changes, but an explanation
