Need viper 1.14 for AIX

[scentoni]

Versions 2.14.0 and 2.20.0 of mockery fail to build on AIX like so:

$ go install github.com/vektra/mockery/[email protected]
# github.com/spf13/viper
../../go/pkg/mod/github.com/spf13/[email protected]/viper.go:457:33: watcher.Events undefined (type *fsnotify.Watcher has no field or method Events)
../../go/pkg/mod/github.com/spf13/[email protected]/viper.go:484:31: watcher.Errors undefined (type *fsnotify.Watcher has no field or method Errors)

due to an issue fixed in github.com/spf13/[email protected]: spf13/viper#1416
