Update grafana to 10.4.14

This is the latest release of the 10.x series and we're currently stuck
on 10.2.2. We can update to 11.x after we're up to date on 10.x.

We bundle this change up with an update to run on Noble. The plan is
we'll put the old 10.2 focal server in the emergency file, land this
change, then add a new Noble server to inventory. This should allow us
to easily rollback to 10.2 if Noble with Grafana 10.4.14 don't work for
some reason. Basically killing two birds with one stone here and getting
a safer upgrade process out of it.
