Control widths of tabs in Datamodel Tool

[CelineTrammi]

Description

It would be nice to be able to stretch the desired width in the Studio Designer for Datamodel changes. When working with Altinn Apps, I often use more than one window open. As such the total width is smaller. I would love a feature where I could have more control over which of the "tabs" that becomes truncated, or at least a way to toggle hide/unhide for the tab I am not interested in keeping open

We have a similar issue on the forms editor, https://github.com/Altinn/altinn-studio/issues/12787. Should probably solve those two in the context.

Blocked by #12787 and should be implemented the same way.
