The module doesn't support using TLS_JA3_FINGERPRINT in enforce on key

[NOT A CONTRIBUTION]

It seems the module doesn't support setting TLS_JA3_FINGERPRINT, while the documentation [1] and examples [2] show it's possible.

│ Error: expected rule.60.rate_limit_options.0.enforce_on_key to be one of ["ALL" "IP" "HTTP_HEADER" "XFF_IP" "HTTP_COOKIE" "HTTP_PATH" "SNI" "REGION_CODE" ""], got TLS_JA3_FINGERPRINT

│ Error: expected rule.60.rate_limit_options.0.enforce_on_key_configs.0.enforce_on_key_type to be one of ["ALL" "IP" "HTTP_HEADER" "XFF_IP" "HTTP_COOKIE" "HTTP_PATH" "SNI" "REGION_CODE"], got TLS_JA3_FINGERPRINT

Would it be possible to extend the module to support that as well? Thank you
