feat(triage signals): New kick_off_seer_automation flow [feature flagged]

[Mihir-Mavalankar]

PR Details

• I had to revert by last fixability PR. I am going to address it separately after this PR - made a ticket for that: https://linear.app/getsentry/issue/AIML-1650/address-fixability-issue-in-the-new-automation-flow
  • Also mentioned in the TODO comment
• This PR just creates the new automation flow for triage signals behind a feature flag.
• Reference diagram: https://miro.com/app/board/uXjVJqn1-fQ=/?focusWidget=3458764648325594380
• Also make run_automation a public method now since we directly use in a task.
