fix(ext/node): fix prismjs compatibiliy in Web Worker (#25062)
PrismJS uses `WorkerGlobalScope` and `self` for detecting browser's Web
Worker context:
59e5a34713/prism.js (L11)

Now the detection logic above is broken when it's imported from Deno's
Web Worker context because we only hide `self` (Prism assumes when
`WorkerGlobalScope` is available, `self` is also available).

This change fixes the above by also hiding `WorkerGlobalScope` global in
Node compat mode.
