Support monaco-editor@0.53+

Hi!

I see that across the repo `monaco-editor` is pinned to `0.52.2`.
I know that they changed how worker are loaded in `0.53.x` and onwards, and I wanted to know if you plan to support it.

Thank you

Search the repository for the monaco-editor@0.52.2 pin and inspect the editor worker-loading entry points; the issue names no specific files or tests. Update support for monaco-editor 0.53+ and verify that workers load correctly without regressing the GraphiQL editor.
