Add version/hotfix override #9869

Scenarios:

• I installed the official release and want to load the page without hotfixes
• I installed the local version (0.0.0) and want to load the hotfixes

For the first one, I could add a "temporarily disable hotfixes" button in the options, using webext-storage-cache for 6 hours.

The second one could be possible by removing a couple of isDevelopmentVersion checks and just forcing the fetch and cache of hotfixes for a specific version, e.g. button -> prompt('what version to preload?')

I never implemented this because:

• the first one is rarely useful
• the second one can already be achieved by editing the manifest.json locally
