bare tags and kong: tags don't work together in an embedded struct

[dgunay]

This particular setup doesn't behave the way I want: https://go.dev/play/p/vYCFMxlM9Lk

(gist in case the playground link ever expires https://gist.github.com/dgunay/3755d6956bc2c35ce11b26961c8fe97b)

I want to be able to reuse the behavior "either --name=STRING or --pick are required", by embedding the struct into other commands. It works, until I add the kong:"predictor=session-name" tag, then the xor requirement no longer works.

I am able to work around it by changing all the tags to go under a kong: tag. Changing the predictor tag to be bare does not work (probably due to some implementation detail of https://github.com/WillAbides/kongplete.)

Anyway, this contradicts the readme:

kong/README.md

Both can coexist with standard Tag parsing.
