Simplify MSSQL Server testcontainer setup for integration tests

[yhao3]

Description

• Explicitly accepting the license programmatically: This eliminates the need for users to manually create a container-license-acceptance.txt file, streamlining setup.

• Removing outdated comments: The configuration file has been updated to remove comments about manual license acceptance, as this is now handled automatically.

Additional notes

• This change is aligned with the official Testcontainers documentation for MSSQL Server modules.
• The documentation states that license acceptance can be done either programmatically or via a resource file, and this PR adopts the programmatic approach for a more streamlined experience.

I am not sure we should generate with it enabled.
We cannot accept the license for the end user.

Maybe we should generate commented.
