[zhlsunshine]

Description

It's okay now for example of ChatQnA on both xeon and gaudi platform, and I also add the platform switcher on matedata label with label gmc/platform. Test section contains the deployment snapshots.

Moreover, I also validate the example by sending validated requests for them.
