[SPARK-55590][SQL][TESTS] Add `mysql-connector-j` test dependency to
`sql/core` module
### What changes were proposed in this pull request?
This PR aims to add `mysql-connector-j` test dependency to `sql/core`
module.
### Why are the changes needed?
`JDBCSuite` requires `mysql-connector-j` client. Previously, it seems that
`MariaDB` connector are used unintentionally. We should fix this.

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