Add Table TableGroup Support

[gogojson]

Is your feature request related to a problem? Please describe.
I’m using the DBML Visualizer plugin in VS Code to create and view database diagrams. While DBML supports TableGroup for logically grouping related tables, the plugin currently does not render these groups in the visualization.
This makes it difficult to visually organize large schemas and clearly communicate how certain tables relate to each other in terms of domain or context.

Describe the solution you'd like
I would love for the DBML Visualizer to support TableGroup by:
• Rendering grouped tables together in a container or bounded region
• Labeling the group with the name provided in the DBML (e.g. TableGroup users)
• Optionally allowing the group to be collapsible or stylized

Describe alternatives you've considered
I am using dbdiagram.io

Additional context
• DBML officially supports TableGroup: https://dbml.dbdiagram.io/docs#tablegroup

@BOCOVO / @togo01 is there anything one can do to support this feature request?

We're using the plugin at my workplace and it's a really great support.
Only problem is we have a lot of tables in one DBML and the plugin doesn't visualize Table groups.

As a first workaround it would be helpful, if it would "skip" table groups because at present, we do need to comment them - otherwise no chart is shown. (We visualize in another software - which supports table groups - in addition to the VS-Code plugin)
