[UD] Avoid re-rendering the Workspace Details page

[akurinnoy]

Is your task related to a problem? Please describe.

This is a technical debt issue. The PR for improving devworkspaces support introduces the bug that the whole workspace details page gets re-rendered each time the workspace is updated. That's the regression and it brings inconvenience to the devfile editor usage.

Describe the solution you'd like

The solution is to provide necessary changes to the nested components without re-rendering of the root page component.
