Remove use of URL from node:url

[lxcid]

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and couldn’t find anything (or linked relevant results below)
• If applicable, I’ve added docs and tests

Description of changes

Continuation from #70.

In v7, we can use this package in browser, but because of the 'node:url' import in v8, browser support is no longer available. The initial dismissal of the issue #70 was due to typescript complain, this PR attempt to address that in hope that it get merged and browser support is re-enabled again.

Changelog

• Pinning TypeScript to v4.4.x as it is hanging the compiler, see tsc 4.5 hangs with unist-util-visit package (works fine with 4.4.4) microsoft/TypeScript#46900
• Fix figure figcaption test case which is broken, somehow \ was added to the filename, but i checked the html there's no such character. Feel free to correct me if i'm wrong.
• Remove import {URL} from 'node:url', from my use case, typescript didn't complain, but if it ever complain, my solution is to introduce DOM to libs in tsconfig.

browser support is no longer available.

People are using this in browsers. #70 also mentions that this is likely a problem with your bundler that can be solved.

from my use case, typescript didn't complain,

You ran npm test after your change and nothing happened?

@wooorm yep! it pass for me. did it fail for you? The github action pass as well, i have to downgrade typescript to 4.4 and fix one broken test case though, otherwise everything is good.

Hmmm, did you make any configuration to ignore node:url when bundling? I'm using webpack/babel and is using fairly modern configuration though. I don't mind adjusting my webpack/babel configuration.

Ohh it’s been a years old issue with TypeScript, and they solved it 5 days ago: DefinitelyTyped/DefinitelyTyped#58277 (comment)
