fix(action): update fetch-depth parameter to fetch only the last commit

[gauthierpetetin]

Description

Update fetch-depth parameter to fetch only the last commit, rather than the whole commit history

We used to fetch the whole commit history which wasn't useful for this github action. This change allows to fetch only the latest commit which makes the workflow more efficient. This improvement is not a game changer, but it's worth doing it as the workflow runs quite often (multiple times for every PR), as it's triggered every time PR labels are updated.

Same PR for Extension.
