fix: nested stylesheets should have absolute URLs (#1533)

Browse Source 
* Replace relative URLs with absolute URLs when stringifying stylesheets

* Add test to show desired behavior for imported stylesheets from seperate directory

* Rename `absoluteToStylesheet` to `absolutifyURLs` and call it once after stringifying imported stylesheet

* Don't create the intermediary array of the spread operator

* Formalize that `stringifyRule` should expect a sheet href

* Ensure a <style> element can also import and gets it's url absolutized

* Handle case where non imported stylesheet has relative urls that need to be absolutified

* Clarify in test files where jpegs are expected to appear in absolutified urls

* Move absolutifyURLs call for import rules out of trycatch

* Add a benchmarking test for stringifyStylesheet

* Avoid the duplication on how to fall back
