[GithubAction] Push Operator Node Images

[siddimore]

Why are these changes needed?

Needed to push operator node images to public ghcr.
Invoking Role: Oncall
Steps:

1. Verify Test Results for PreProd run and obtain commit-sha for that (TBD: one place look up for commit-sha to TestResult)
2. Provide Commit Sha and Release Tag as input parameters to this action
3. Run workflow

Alternative Considered:

1. Writing this github action in eigenda-devops
2. PreProd environment rel has a github action(cronjob) which will publish eigenda components update and run some test
3. If this PreProd environment rel succeeds then publish Node specific images from ECR to GHCR
