Fixes for #15557

#15597

[Copilot]

Pull request overview

Updates the GitHub Actions workflow responsible for building and redeploying the testing-xtm-one environment, aligning the restart step with the intended AWX job template/variables for that deployment path.

Changes:

• Renamed the workflow to reflect that it performs a deploy/restart (not generic “CI”).
• Switched the AWX job template invoked for redeploy from the previous deploy template to a rollout-restart template.
• Updated AWX extra_vars payload keys from instance to solution for the restart job.
