Rollup merge of #57504 - GuillaumeGomez:re-enable-history, r=QuietMisdreavus

Re-enable history api on file:// protocol

Fixes #57135.

I tested locally on chrome (since it was the browser having issues with history management on `file://` protocol) and it worked fine so I guess we can re-enable it.
