Modify the template to let the user choose whether they want the database container or not

Follow on from : #17262

The current template always creates both the Dockerfile for the site and the database, but actually it's not useful to always create the database. I propose changing the template to separate the website and database container. Happy to do it myself

Proposal is that I add the following which will generate the Umbraco database container for SQL server.

dotnet new umbraco-database -P "MyDbContainer"

This will give users the choice if they want to use a DB container, or a DB service (when hosted on Azure) or SQLite. I also propose that the docker compose template is modifies so that we include a volumn for SQLite, to allow users who want to use SQLite to generate a DB
