Add self-hosted packages to the https://packages.ecosyste.ms/

[mgovers]

For instance, homebrew-core only contains some 8000 packages that can be installed directly using brew install foo , but a self-hosted package can also be downloaded easily using brew install foo/bar/baz. However, that does not appear to be found by ecosyste.ms. I understand that searching the web for all possible self-hosted packages would not be doable, but it would be nice if there was a way to contribute such self-hosted packages to the overview.
