Replace sync-request with sync-fetch

[ypconstante]

Is your feature request related to a problem? Please describe.
Today happy-dom uses sync-request to handle situations were a synchronous request is necessary, but this library isn't maintained anymore (last release was 4 years ago), and requires a lot of packages not used by happy-dom or it's dependencies.

Describe the solution you'd like
Migrate to sync-fetch, which is an actively maintained library that uses node-fetch, like happy-dom, which should help reduce happy-dom install size by 3Mb

Describe alternatives you've considered

Thank you for reporting @ypconstante! 🙂

Me and @Mas0nShi are working on a fix for this in a related PR:
https://github.com/capricorn86/happy-dom/pull/520/files#diff-532eacee8d4b349453e921fd5fdbd2d2f191868e1242b03a27f9f6365be7fe1fL36

We will replace sync-request with a very minimal custom solution.

Re-opening as I just noticed that the dependency in package.json is still there.
