Add a git tag and/or PR number to artifact and PR merge build filenames #8321
Description
When we merge a PR, firmware are uploaded to S3. Before that, artifacts are available.
The files have names like adafruit-circuitpython-8086_commander-en_GB-20230803-95c0867.uf2. This is not all that helpful. At the moment, when we are making both main and 8.2.x PR's, it would be nice if the names included the nearest tag and possibly the PR number.
