[Feature Request] Prefer release artifacts over building from submodules for the purposes of build container images

[jbreiding]

Is your feature request related to a problem? Please describe.

This repo depends on submodules to build binaries that are already built and should be artifacts tagged as releases on the respective submodule repos.

Rather than rebuilding this repo should be downloading and extracting the tar ball to the respective container image.

Describe the solution you'd like

Replace submodules with shell script to curl and extract taking in the respective release versions as build args.

Additional context

Temporal repo already emits go-releaser artifacts with release tags.
tcl and ui-server must do the same.
I will take on the work to land those changes in the respective repos and then work to reconcile those changes into this repo.
