Rollup merge of #70224 - GuillaumeGomez:clean-up-rustdoc-js-testers, r=Dylan-DPC

Clean up rustdoc js testers

I realized after the improvement made by @ollie27 on the rustdoc-js-tester that a lot of code was actually duplicated. This PR intends to remove this duplication, making it simpler to update in case of future main.js updates.

r? @ollie27
