[Ruby] red-arrow fails to install on arm64 macOS with rubygems-requirements-system

[amoeba]

Describe the bug, including details regarding any error messages, version, and platform.

When using red-arrow with rubygems-requirements-system on arm64 macOS, installing system requirements fails. There are at least a few ways to fix this so I'm filing an issue to discuss.

My Gemfile:

source "https://rubygems.org"

plugin "rubygems-requirements-system"

gem "activerecord-adbc-adapter"

My error,

$ bundle

An error occurred while installing red-arrow (24.0.0), and Bundler cannot continue.

In Gemfile:
  activerecord-adbc-adapter was resolved to 0.0.1, which depends on
    red-adbc was resolved to 1.11.0, which depends on
      red-arrow

I see it errors out when trying to find arrow-c-glib on conda-forge which fails because we don't have arm64 packages on conda-forge. But the real thing I wanted was for rubygems-requirements-system to ignore the failure and continue down to try to install with homebrew.

To fix this, I think we could:

1. Publish arm64 binaries to conda-forge
2. Remove the conda options from the requirements since Linux users will already get covered by apt/yum/etc
3. Improve rubygems-requirements-system to have fallback behavior in this case (package manager and package name is available but wrong platform)

Oh, sorry. I didn't notice the case.

Let's use the 1. option for this case: conda-forge/arrow-c-glib-feedstock#42

But the 3. option is also interesting. I'll add support for specifying platform explicitly by users instead of auto fallback. If the detected platform isn't expected by users, users will want to specify their platform explicitly.

Let's use the 1. option for this case: conda-forge/arrow-c-glib-feedstock#42

It's merged. This problem must be solved.
