drone(docker-driver): Fetch tags before pushing image during release (#…

…10664)

**What this PR does / why we need it**:
We realized, loki-docker-driver image was not being pushed after 2.8.2.
And looking into it's drone pipeline and comparing it with other steps,
docker-driver step is not fetching the tags,[ thus the final hash
calculated to push is some HEAD
branch.](https://github.com/grafana/loki/blob/main/tools/image-tag#L13-L14)

e.g: even if we have tag 2.9.1, it pushes only with latest HEAD commit
hash.

This PR fixes it.

**Which issue(s) this PR fixes**:
Fixes #<issue number>

**Special notes for your reviewer**:
I would prefer this instead of
#10663. Because that would make
fetching tags more repetitive in all the drone tasks (can also be
expensive in terms of running time if we put all together)
