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!

まず MSSQLServerContainer を読み、既存のデータベース名設定パターンを探します。アプリケーション接続の前にコンテナがどのように初期化されるかを追跡し、関連する統合テストを実行します。withDatabaseName() が master ではないデータベースを作成して使用し、要求された設定を利用できるようになれば完了です。
