Improve Score Reporting: Deps-Update-Tool should check for tool activity

[azeemshaikh38]

Is looking for the presence of a config enough of an evidence to rate a repository at 10? Should we maybe tighten this check a bit more and make sure that there have been recent commits by these tools?

I think we used to have a tracking issue for this - I can't find it so maybe not :)
One reason we postponed implementation was because it's not clear how often a PR could be expected to be merged. This depends on repo activity, for example. Since scorecard checks for 30 commits, there is a risk that the results would oscillate between different scores, depending on whether we find a PR or not.
