ACR Purge

PURGE_CMD="acr purge --filter '.*:^GOLD.*' \
--ago 15d --dry-run"

az acr task create --name PurgeGold1 \
--cmd "$PURGE_CMD" \
--schedule "00 16 * * *" \
--registry "acrdemo2022coreg" \
--context /dev/null

When this schedule runs, it shows that the repository also will be deleted but the expectation is to delete gold tag on all the repositories in the ACR.

Reproduce the Azure Container Registry task with the shown PURGE_CMD and --dry-run first. Trace the purge filtering behavior for the GOLD tag pattern across repositories; done means the dry run reports matching tags for deletion without deleting the repositories themselves.
