Subject: [PATCH] Copy CI workflows from `spf13/viper` repo

This imports the `ci` workflow from
https://github.com/spf13/viper/commits/ab4b05adc65543c13f4b71cf3dc7e2967524f3d1
with one modification noted in the file.

This omits the feedback workflows, as those are not required here.  It
also omits the wasm workflow, as this old snapshot of the code does not
work in that context.
