Message about browser refresh in dropdown

[sammacbeth]

When searching for "firefox windows" the following message appears in the dropdown. The help link goes to https://firefox-source-docs.mozilla.org/setup/windows_build.html#building-firefox-on-windows

We should probably disable this.

It looks like this query provider does this based on certain keywords: https://searchfox.org/mozilla-central/source/browser/components/urlbar/UrlbarProviderInterventions.jsm#65

We could simply disable the provider.
