Ability to remotely disable broken features #3529

Crazy idea, but occasionally we have very breaking bugs that cause frustration: #3527 #2357 #1805 #1148 #2700 etc

These are often fixed quickly, but users have to suffer it until the browser updates the extension, which could be a day later.

We could have a mechanism that pings this repo to check whether a feature should be temporarily disabled. For example inside globalReady

const options = await optionsStorage.getAll();
const hotfix = await cache.get('hotfix');
fetchHotfixesAsynchronously(); // `cache.function` to be run up to ~4 times a day?
Object.assign(options, hotfix);

fetchHotfixesAsynchronously could fetch the content of a dedicated, locked issue with a content like:

false

or

{"cleanup-repo-filelist-actions": false, "unaffected": "20.9.4"}

fetchHotfixesAsynchronously would use looseVersionCompare to compare unaffected with the current version and either store {'cleanup-repo-filelist-actions': false} or {} accordingly.

Notes

Performance: up to 4 fetches a day should make it lightweight enough
Privacy: it would only fetch public content on GitHub, only if you open GitHub
Security: it would only GET JSON content from api.github.com, it doesn't POST anything
