As a shipwright developer, I want to stop relying on service accounts for mounting my secrets at the pod level

[qu1queee]

Idea:

This is coming as an outcome of https://github.com/shipwright-io/build/issues/662. We want this issue as a way to understand the implication of stopping using serviceAccount and referencing that in Tekton TaskRun, in favor of dealing with our secrets directly, without the need of a service account, as seen in:

• Via env vars
• Via volumes
• Via volumes + params.
