Add Algolia querying to fix Homebrew/cask searching

[Bo98]

Works alongside GitHub searching since we don't have every tap on formulae.brew.sh at the moment.

This is basically Homebrew/cask only. It does search Homebrew/core too because they are together in the search index but I don't think there's ever a situation where the tap will be untapped (excluding API mode) and as such we will never need to display those anyway? If I'm wrong: it's only one line to add.

HOMEBREW_NO_GITHUB_API will disable searching on Algolia, like how it disables GitHub searching. Based on the that variable's description, I think that's a reasonable thing to do even though it sounds weird with the name.

Fixes #12557.

I think I'd like to see this replace GitHub searching rather than doing both.

Would be good to handle the API case here 👍🏻

Ok I'll look into integrating cask-versions etc.

Local formula searching with API enabled will work if/when Formula.core_names reads from the JSON file, in which case Algolia querying won't be needed for that setup. I could enable Algolia searching in the meantime however.

This would be trivial to set up, just return Homebrew::API::Formula.all_formulae.keys right? I'd say just go ahead and do that in this PR if you want

Adding other taps to formulae.brew.sh is going to take some time. I'll get around to it sometime this month hopefully.
