fix(worker-window): polyfill CSSMediaRule

Description

Include polyfill for CSSMediaRule (used by hubspot tracking js)

Use cases and why

Hubspot references CSSMediaRule in their JS and it is currently failing because it doesn't exist in worker context. We already have the polyfill for CSSStyleSheet and CSSMediaRule has the same interface so the same polyfill should work!

Looks like CI had an issue installing PNPM. Can a maintainer please rerun the CI checks on this PR?

@gioboa Do you see any issues with adding this?

It looks good to me but I'm no longer on the core team that maintains the library. I'm sorry.

I discovered that microsoft clarity has patched this on their end and I'm not sure this solution makes sense as it only polyfilled the bare minimum of what was needed so I'm going to close for now.

In the end, this should still go in. It wasn't patched in clarity and having this polyfilled inside partytown is arguably a better solution.

Is there any update on this or some kind of workaround ? I'm having issues with GTM including clarity

[AndreAzevedoCoder]

I'm still having this issue with clarity, I think it's a good idea to merge this
