Migrate chart-testing formula to homebrew/core

[crunchtime-ali]

Congratulations! 🎉 The formula chart-testing has been migrated to homebrew-core 🍺
This means that the homebrew community will co-author the formula and the formula is even easier to install (via brew install chart-testing).

What this PR does:

This PR changes the instructions on how to install chart-testing on macOS. It also removes the tap configuration from goreleaser which prevents your own tap to be updated. The formula will be updated by the Homebrew community (e.g. automatically via brew bump-formula-pr chart-testing $VERSION which is triggered automatically by GitLab CI action in one of my private repos).
If you plan to automate chart-testing GitHub releases we can also include a GitHub action that automatically create a PR against homebrew-core. You can see an example on how to accomplish this in the release.yaml here https://github.com/argoproj/argo-cd/pull/3979/files

Here is the accompanying PR in your tap repo: helm/homebrew-tap#1

I don't think my change caused the build to fail. Can someone kick the CI server to retry? Maybe @scottrigby ?

I don't see any advantage here. I'd rather keep things under our control. Why would it make sense to rely on a CI job in one of your private repos?

the advantages are:

• the binaries are bottled for the current macOS version and the former two
• the community makes sure that the formula and chart-testing itself works with the new architecture (welcome Apple Silicone) without you lifting a finger (see macOS 11 Big Sur compatibility on Apple Silicon Homebrew/brew#7857)
• you can check out installation analytics for the formula if you are interested in it

Of course, you don't want to rely on a CI job in one of my public repos but you can rely on the active Homebrew community to keep your formula in the best shape possible while you worry about the chart-testing project itself.
Since chart-testing releases are not automated there was no point in adding a CI job to this repo. If you are interested in switching the build and release process to GitHub actions I could prepare another PR independent of this one.

If you still want to keep everything under your own belt feel free to close this PR.

@crunchtime-ali Thanks for clarifying and thanks for your effort.

As mentioned on keybase, I think this is a win all around 👍

We only track the top 200 formulae for now, which doesn’t include chart-testing. However, we do track two of your dependencies, go and helm.

As soon as you see both go and helm listed 🥉 (or better) on Homebrew/brew#7857, chances are chart-testing is going to work just fine, too.
