[Bug] Create Rule CLI Crashes on Required Arg

[Mikaayenson]

Issues

#3096

Summary

Refactors the required --> is_required function argument to avoid name collision by new fields like alert_supression in our API schemas.

Testing

Run the CLI python -m detection_rules create-rule test. Should successfully generate a toml file with no errors.
