message: [fs-detectors] Remove "solidstart" framework from FS API v2 detection
  "solidstart" framework doesn't need to use the FS API v2 Builder anymore since:
  1) Newer versions output Build Output API v3
  2) Older versions that output FS API v2 will be handled by the compatbility shim that was added in
