Consider hiding `browserlists` warning

[FrederikBolding]

Users may receive a warning about caniuse-lite being outdated when using the CLI, e.g.

Browserslist: caniuse-lite is outdated. Please run:
  npx update-browserslist-db@latest
  Why you should do it regularly: https://github.com/browserslist/update-db#readme

Since we target quite old browser versions for the extensions sake we should consider hiding this warning in the CLI.
