Goal: 

• We want to remove all occurrences of "(cc <!subteam^S07DPHWCHC6>)" from slack messages in all rhel-ai repos. example here https://gitlab.com/redhat/rhel-ai/disk-images/nvidia-bootc/-/blame/main/.tekton/nvidia-bootc-iso-disk-image-push.yaml?ref_type=heads#L39

Acceptance Criteria:

• The goal above is achieved and no more messages with "cc .." are in the #rhel-ai-notifications channel
• The ecosystem-rhelai-qe slack group is no longer pinged on every message
