build: fix github wf to generate metadata bundle

[sicoyle]

Description

If we leave the workflow definition file as is, then it will not work. It will err with The specified go version file at: go.mod does not exist. This is because the workflow steps set up Go referencing a go mod file before actually downloading the repo code that contains the go mod file that the precursor step needs. This PR fixes that issue, and bumps setup-go versions.
