Libraries dependencies for media_library

Please open a merge request.

What's the issue exactly though?

If a UI issue the summary should be updated to include before/after screenshots, also proposed solution.

Otherwise the variables in the css like '--vertical-tabs-menu-width' are not defined.

The variable --vertical-tabs-menu-width is defined in the variable.pcss.css file, and it is available globally. So there's no need to add the dependency of claro/vertical-tabs

To clarify, are there scenarios where the vertical-tabs-menu-width variable isn't available globally in other themes, or is this issue limited to Claro? It might be helpful to confirm if adding the dependency solves similar cases across custom themes or if this fix should be strictly scoped to the Claro theme.

The Claro theme was approved for removal in #3576460: [policy, no patch] Deprecate and remove Claro.

This is Postponed. The status is set according to two policies. The Remove a core extension and move it to a contributed project and the Extensions approved for removal policies.

The deprecation work is in #3576668: [meta] Tasks to deprecate Claro and the removal work in #3584638: [meta] Tasks to remove the Claro theme.

Claro has moved to contrib

But IS needs to be updated before it can be worked on. Especially screenshots please.
