Unfortunately Renovate is currently mal-functioning, as we are hitting
this error: https://gitlab.com/gitlab-org/gitlab/-/issues/336657

Therefore we manually bump the GitLab UI version to the latest major.
This should have no impact on the GitLab project (apart from smaller

we need to migrate have been taken care of, _before_ we started merged
the new major release.

This removes an unnecessary yarn resolution, as monaco-editor@0.25.0 is

Add support for rendering and editing inline content inside content
editor. Also adds a table creator that lets you create a custom sized
table with MxN rows where M, N range between 1 and 8.
