Bump supported MySQL versions (#40892)

Browse Source 
Fixes #40975.

8.0.32 (was running in Aurora managed cloud at the time) -> 8.0.39 (what
we're running now) 8.0.36 -> 8.0.44 (latest 8.0.x version supported by
Aurora; holding off on 8.0.45 until Aurora supports it) 8.4.7 -> 8.4.8
9.5.0 -> 9.6.0

Also bumped the supported Aurora version from 3.07.0 to 3.08.2 to match
what we're running in managed cloud right now

Fleet might work on older patch versions but we'll no longer dev/test on
them. MySQL 9.x not testing previous minor versions matches with our
previous approach for that version.

Since these are all patch/minor bumps (and the overnight build cases are
patch bumps/are covered by AWS envs) automated testing should be
sufficient here.

Fleet uses MySQL extensively as its main database. Many cloud providers (such as [AWS](https://aws.amazon.com/rds/mysql/) and [GCP](https://cloud.google.com/sql/)) host reliable MySQL services which you may consider for this purpose. A well-supported MySQL [Docker image](https://hub.docker.com/_/mysql/) also exists if you would rather run MySQL in a container.
For more information on how to configure the `fleet` binary to use the correct MySQL instance, see the [MySQL configuration](https://fleetdm.com/docs/configuration/fleet-server-configuration#mysql) documentation.
Fleet requires at least MySQL version 8.0.36, and is tested using the InnoDB storage engine [with versions 8.0.36, 8.4.7, and 9.5.0](https://github.com/fleetdm/fleet/blob/main/.github/workflows/test-go.yaml#L51).

There are many "drop-in replacements" for MySQL available. If you'd like to experiment with some bleeding-edge technology and use Fleet with one of these alternative database servers, we think that's awesome! Please be aware they are not officially supported and that it is very important to set up a dev environment to thoroughly test new releases.
