ec5862a2 - Re-apply: workflows: Use main-branch-only environment when using ISSUE_SUBSCRIBER_TOKEN (#179990) (#193801)

Re-apply: workflows: Use main-branch-only environment when using ISSUE_SUBSCRIBER_TOKEN (#179990) (#193801) This way we can prevent the secret from being used in user branches. We originally reverted this because it was spamming the PRs with 'deployment' messages. GitHub has added a new feature to disable these messages, so it should be safe to re-apply this.
