Normalize cache plugins for Go compilation & image construction

[richscott]

The test, lint, and release workflows use the magnetikonline/action-golang-cache plug-in, however, the buildworkflow uses the and actions/setup-go and actions/cache plug-ins - both could be replaced by using just magnetikonline/action-golang-cache.

• Instead of specifying go-version: '1.20', it could use go-version-file: go.mod to have it automatically select the Go version from go.mod
• build.yml uses actions/cache just for caching /home/runner/go/bin - we could also use it for $HOME/.cache/go-build and $HOME/go/pkg/mod - see https://github.com/actions/cache/blob/main/examples.md#go---modules
