test: update payload golden for AIO to reflect reduction in size (#50107)

The `main` bundle fell below the threshold. No actual investigation
was done here because it's a reduction in size, and the AIO size
matches the `AIO-local` size now. This is expected because the latest
RC closely matches the `main` branch (or even is equivalent at this
point).
