💡Provide binaries on pkg.cloudflare.com

**Describe the feature you'd like**

Community reference: https://community.cloudflare.com/t/cloudflared-automated-download/418848

Someone suggested that the binaries should be available somewhere other than GitHub's releases.

As https://pkg.cloudflare.com only provides the `deb`/`rpm` packaging for use with package managers, it'd be good if it could also expose the same binaries that are published in GitHub releases.

**Additional context**

At a glance, it looks like it'd be pretty easy to add that functionality into https://github.com/cloudflare/cloudflared/blob/master/release_pkgs.py since it will already have access to the built binaries.

I guess the question is which path would they be exposed on, i.e https://pkg.cloudflare.com/cloudflared/binaries/

It'd also be good for a hash/checksum to be published alongside.
