Alexlovelltroy/build improvements

[alexlovelltroy]

Adding build automation from the work I did for smd that leads to better version reporting, multiarch containers, and native packages

[davidallendj]

I made two inquiries about the changes, but neither are necessarily blockers.

We should probably also update the README with build instructions using goreleaser (e.g. setting the env vars).

Commenting here for posterity: .Arm64 was introduced in Goreleaser v2.4 so at least that Goreleaser version is required (see: https://goreleaser.com/customization/templates/#single-artifact-extra-fields).

Otherwise one will get the following error:

  ⨯ release failed after 2m34s               error=template: failed to apply "dist/bss_{{ .Os }}_{{ if eq .Arch \"amd64\" }}{{ .Arch }}_{{ .Amd64 }}{{ else if eq .Arch \"arm64\" }}{{ .Arch }}_{{ .Arm64 }}{{ else }}{{ .Arch }}{{ end }}/boot-script-service": map has no entry for key "Arm64"

The build works using Goreleaser >=2.4 and I was able to test the amd64 container. I haven't been able to test arm64 yet.

Tested goreleaser on the same amd64 machines and worked on all of them.

I obviously couldn't test the GitHub actions stuff, but found a small thing that should be fixed before merging.

Also, can we add the environment variable setting instructions for Goreleaser to the README (e.g. this)? I think the instructions are helpful for building locally, but also it's useful to, when building locally, do something like

eval $(grep ^export README.md)

to automatically source those variables.

Also, I am seeing go.mod and go.sum changes when I run goreleaser.

Everything is resolved, LGTM.
