release kargo-render binary

[joaoestrela]

Currently, only the Docker image is published. It would be great to also provide a binary release. Currently, it's challenging to pass through Helm credentials in a GitHub Action because it's within a container with its own Helm installation.

Having a binary release would allow the kargo-render binary to be used within the workflow authentication context.

Kargo proper just did something about this a few days ago: akuity/kargo#1977

I had been imagining that we'd soon create a native way for chart repo creds to be passed directly to Kargo Render as well, but hadn't yet put much thought into how.

On some level, I'd prefer solving that over simply publishing the binary, since there is a reason that we don't. (Packaging it in an image with git, helm, and kustomize binaries is the easiest way to guarantee Kargo Render has compatible versions of those binaries available to it.)

I'll start thinking about a clean way of passing the creds through.

Fair points.
My suggestion was intended as an additional option for those who might prefer a more customised approach, but I guess that compiling it themselves is a viable solution.
Thanks!

You can also copy it out of a container as long as you're looking for linux/amd64 (or linux/arm64). Presumably in an Action, linux/amd64 would be exactly what you need.

To put some closure on this, solving for #226 will obviate the need for this.
