Bump versions of external dependencies:

- Remove preview wildcard for Oracle MySQL EF Core package
- Update MySqlConnector to 2.5, which explicitly targets .NET 10
- Update MySql.Data to 9.6, which explicitly targets .NET 10

The above aligns with the versions used by the latest NetCoreToolTemplates package.
