fix: (backport) enable markdown editor in libraries (#2098)

* fix: enable markdown editor for problems in libraries too

This fix is also achieved on master via 5991fd3997 / https://github.com/openedx/frontend-app-authoring/pull/2068 but this is a simpler fix, not a direct backport of that refactor.

* fix: remove duplicate markdown_edited save request (#2127)

Removes the unnecessary duplicate save  request of markdown_edited
value to the backend.

Part of: https://github.com/openedx/frontend-app-authoring/issues/2099
Backports: 62589aea50
