LibWeb: Use the correct document URL in DOMParser.parseFromString()

Browse source 
We were hard-coding "about:blank" as the document URL for parsed HTML
documents, which was definitely not correct.

This fixes a bunch of WPT tests under /domparsing/ :^)

(cherry picked from commit 55f58eea99c0429dcc39cd0430fafa60eecf5542)
