v4.12.9

Fixed

• Fix analyzer RCS1090 (PR)
• Fix analyzer RCS1124 (PR)
• [CLI] Fix command generate-doc (PR, PR)

Changed

• Update analyzer RCS1077 (PR)
  • Do not suggest to change list.FirstOrDefault(predicate) to list.Find(predicate).
    Performance gain is negligible and actually FirstOrDefault can be even faster on .NET 9 (see related issue for more details).
