Create Next-Build Workflow to Update Helm Chart Container Image Version

[olivereri]

Requirements

When code updates are released and a new container image is built the helm chart in the application manifest repository needs to be made aware of the change. This ticket will establish a Github Actions (GHA) workflow to modify and commit a change to the Next-Build helm chart with the update image tag.

Background & implementation details

Application Manifest Update:
https://github.com/department-of-veterans-affairs/vsp-infra-goldilocks/actions/runs/4266039617/workflow

This can be triggered by the successful completion of the Create Production Tag workflow: https://github.com/department-of-veterans-affairs/next-build/actions/workflows/production-tag.yml

See that workflow for an example of the Create Production Tag workflow being triggered by a successful run of Continuous Integration on the main branch.

This workflow will need to be able to identify the current leading tag. This could be exported from the Create Production Tag workflow, or it could be found by querying the repo.

We need to grab the latest tag of the next-build repo and build using that.
