Migrate transport versions 8841050 through 8841041 (elastic#135555)

jdconrad · jdconrad · commit 392b07b363d2 · 2025-09-26T15:47:27.000-07:00
This has an unusual case where we took a dead primary id
 and combined it with a patch only id for a change that
removed a boolean in 8.19. This worked because the
primary id was created prior to the 9.1.0 release, so this
still guarantees compatibility with all upgrade paths.
