Don't require being logged in to call help command

[chrisscott]

Description

When logged out or on a fresh install, the help command was blocked from running:

===  error

▸    Not yet configured. Try auth0 login.
exit status 1

Testing

The main help command, help on a subcommand, and --help flags should all return help instead of an error to log in:

go run cmd/auth0/main.go logs list --help
go run cmd/auth0/main.go logs --help
go run cmd/auth0/main.go logs help
go run cmd/auth0/main.go help logs
go run cmd/auth0/main.go help
