Implement withDatabase() in MSSQLServerContainer

Hello,

First of all, thanks for your great work!

I have a requirement to set READ_COMMITED_SNAPSHOT ON in the MSSQLServer database, and due to a MSSQLServer limitation that can't be applied to the default master database:
ALTER DATABASE master SET READ_COMMITTED_SNAPSHOT ON
throws
SQL Error [5058] [S0002]: Option 'READ_COMMITTED_SNAPSHOT' cannot be set in database 'master'.

This setting prevents read locks from being created and is the default setting in AzureSQL DB - in my case with testContainers my integration tests intermittently fail with CouldNotAquireLockException because of that.

For this to work OOTB for me I think the MSSQLServerContainer class would have to have the withDatabaseName() method implemented, and add the logic for creating the database before letting the application code connect to it.

I managed to get by by subclassing the MSSQLServerContainer, but it would be great to have it OOTB.

I can provide a PR if that's helpful.

Thanks!

Beginne mit dem Lesen von MSSQLServerContainer und suche nach vorhandenen Mustern für die Konfiguration des Datenbanknamens. Verfolge, wie der Container initialisiert wird, bevor Anwendungsverbindungen hergestellt werden, und führe die relevanten Integrationstests aus. Als erledigt gilt die Aufgabe, wenn withDatabaseName() eine Nicht-master-Datenbank erstellt und verwendet, für die die angeforderte Einstellung verfügbar ist.
