@xumia @liushilongbuaa can you check why PINS submodule is not handled by automation?

[liushilongbuaa]

@yxieca , because sonic-pins used main branch instead of master.
Automation only works for same branch with sonic-buildimage.

This repo also used main instead of master.

Is it possible to add support?
