Build pipeline Service Account migration

This PR changes Service Account used by build pipeline from "appstudio-pipeline" to dedicated to the Component Service Account.
Please merge the Service Account update to avoid broken builds when deprected "appstudio-pipeline" Service Account is removed.

Konflux build/test pipelines are green, I think we can merge this PR.
