Subject: [PATCH] chore(ci): Auto-update versions

Once infra enables RenovateBot, this will
- Create individual PRs for breaking changes
- Combined PRs for compatible changes

This also auto-updates MSRV, like cargo and clap do, to avoid stagnation
and people getting the wrong impression of the MSRV policy from that
stagnation.  This also avoids contributors being hesitant about what
justifies updating MSRV.
