With #13254, we found MSRV updating is broken.
PR #12775 is the last MSRV we got.
That was merged before #12654 and #13106.
That makes #12654 the most likely culprit.
Looking at the logs:
```

Our regex managers have the files matched
but no regex manager packages are found.
I think this means that the name association failed or the regex within
the file content failed.
The differences between cargo and my other projects
- Use of `:`
- `depNameTemplate`
- Presence of `\b`
As a first attempt, I'm going to switch `\b` to `\\b` to be like the
other escaped regex values.
I've been having some repos not updated lately. RenovateBot project's theory is
that its because RenovateBot is scheduled to run once every 3 hours and
checks the schedule at that point while the schedules I use only offers
an exact 3 hour window, making this a race condition. The schedule
originally came from RenovateBot but they changed their polling
schedule.

This will update `Cargo.toml` and `Cargo.lock` at the same time. By
default, all dependencies will be updated, so we pull out the compatible
dependencies into a consolidated PR.
This starts off with the dependency dashboard and automerging being
disabled but explicitly specified to call attention to the potential for
this. We can evaluate these later.
