Update `caniuse` and `browserslist` dependencies
Created by: umpox
Main concern here is updating caniuse
due to a warning we've been getting. Relevant Slack thread: https://sourcegraph.slack.com/archives/C01LTKUHRL3/p1634557982207800
npx browserslist@latest --update-db
Also updated browserslist
because why not :)
