Since the latest update to urfave/cli, it looks like we need to make some adjustments to the sources:

# github.com/urfave/cli-docs/v3
/var/tmp/go/pkg/mod/github.com/urfave/cli-docs/v3@v3.0.0-alpha5/docs.go:273:16: flag.GetValue undefined (type cli.DocGenerationFlag has no field or method GetValue)
/var/tmp/go/pkg/mod/github.com/urfave/cli-docs/v3@v3.0.0-alpha5/docs.go:400:21: flag.GetValue undefined (type cli.DocGenerationFlag has no field or method GetValue)

I'll take care of it ASAP
