tools/get_release_contributors.py: Clarify docs and ignore ImgBotApp & actions-bot

[hoffie]

Updates the tools/get_release_contributors.py release helper script:

• to clarify usage (we missed the website contributors in the first run)
• update usage for the new website process (no more translate* branches)
• to ignore two more bot users which should not be mentioned.

CHANGELOG: Internal: Improved release contributor tooling

Using --graph might make the log easier (not sure on that). Also specifying a --format that limits the result to one line per commit, so long as the info is sufficient (if you're not generally a git user, you may not be familiar with configuring your got log format). RELEASE: should probably be in quotes to show it's a literal to search for.

Hm, tried with --graph, not too convinced about the benefits in this case.

Added --oneline

Done.

Looks like actions-user also needs to be ignored:

It's not that much...
