Disable parallel deployment build in GitHub Actions pipelines

[jgrandja]

We need to ensure that the deployArtifacts and finalizeDeployArtifacts DO NOT run in parallel.

This can be achieved by adding the --no-parallel argument and also by splitting the deployArtifacts and finalizeDeployArtifacts into separate commands.

See this commit 651c94b on what changes need to be applied.

@jgrandja If needed, I'm available to help with this task. It's for the deploy-pipeline-test branch, right?

[jgrandja]

That would be great @ThomasVitale ! Yes, it's for the deploy-pipeline-test branch.

@jgrandja I've just opened a PR with the change.
