[SPARK-48874][SQL][DOCKER][BUILD][TESTS] Upgrade MySQL docker image…

… version to `9.0.0`

### What changes were proposed in this pull request?
The pr aims to upgrade `MySQ`L docker image version from `8.4.0` to `9.0.0`.

### Why are the changes needed?
After https://issues.apache.org/jira/browse/SPARK-48795, we have upgraded the `mysql jdbc driver` version to `9.0.0` for testing, so I propose that the corresponding `mysql server docker image` should also be upgraded to `9.0.0`

### Does this PR introduce _any_ user-facing change?
No.

### How was this patch tested?
Pass GA.

### Was this patch authored or co-authored using generative AI tooling?
No.

Closes apache#47311 from panbingkun/mysql_image_9.
