Homebrew formulas update not working on self-host environment

[quike]

What would you like help with?

I think I found a bug

How are you running Renovate?

Self-hosted

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

GitHub & Artifactory - renovate: stable 37.421.0 (bottled)

Please tell us more about your question or problem

Currently homebrew integration only supports gems stored within github.com hostname
https://github.com/renovatebot/renovate/blob/main/lib/modules/manager/homebrew/extract.ts#L67
So anyone creating internal brew within self hosted environments (like GitHub Enterprise, Artifactory repos....) won't be able to make renovate work for its self defined gems.
In our usecase, we create and store gems into gems repos at self-hosted artifactory. When we try to make reference to those url, renovate complains with an unsupported-url.

Hi there,

A maintainer reviewed the information, and decided that this is not a bug. To avoid confusing others, we will close this Discussion. Please keep reading as there is good news too!

The good news is that the maintainer likes your idea, in general. Please create a new Suggest an Idea Discussion. Feel free to copy/paste what you need from this Discussion. Please focus on the feature request: explain what Renovate should do, and how Renovate can know when/what to do. We may convert that Discussion to an Issue when it is ready. Note that you will still have to wait for a maintainer, or someone else, to do the work needed for your feature.

Why are we closing your Discussion? For us, bug reports are about things that are not working as intended, or things that are not working as described in the docs. What you found may be bad behavior, but we do not think it is a bug.

For more details, please read our development docs about bug handling.

Thanks, the Renovate team
