feat: auto-detect the value of the no-squash option (#118)

The auto-no-squash option is added to:

* backport all the commits when the pull/merge request has been merged
* backport the squashed commit otherwise

It is equivalent to dynamically adjust the value of the no-squash
option, depending on the context.

The no-squash option is kept for backward compatibility for a single
use case: backporting the merged commit instead of backporting the
commits of the pull/merge request request.

Detecting if a pull/merge request was squashed or not depends on the
underlying forge:

* Forgejo / GitHub: use the API to count the number of parents
* GitLab: if the squash_commit_sha is set, the merge request was
  squashed

If the pull/merge request is open, always backport all the commits it
contains.
