cleanup(get.jenkins.io): remove long-lived SAS token and related outp…

…uts (#654)

This PR removes `mirrorbits` file share long-lived SAS token and related
outputs, replaced by the use of a storage key stored in jenkins-infra
hieradata & charts-secrets.

Verification procedure after merging this PR: ensure update_center job
still passes on trusted.ci.jenkins.io (file share used in sync.sh &
sync-recent-releases.sh scripts)
