feat: Update announcements section of PR comment

[scott-codecov]

Resolves codecov/engineering-team#475

Show the ATS message to applicable repos only and otherwise show info about the browser extension.

• announcements section will still show up to 25% of PR comments that do not have the comment layout overridden in their YAML
• if the ATS announcement applies to the comment then favor that:
  • must not be using ATS already
  • must be a Python repo
  • must have sufficiently large chunks size
• otherwise fallback to one of the other general announcements (currently just the browser comment announcement)
