Describe the problem you'd like to have solved

We are interested on import/export risk assessment configuration on our tenant yaml like the rest of our configurations in order to avoid change this manually.

Describe the ideal solution

Looking into previous issues from this and other repos we found this:

auth0/terraform-provider-auth0#851

Which allows us to change the value of the risk assessment flag, however this value is still not available on the tenant yaml, would be possible to add this flags into the tenant schema?

Alternatives and current workarounds

This flag can be updated manually or using a patch call, but we would like to avoid this in order to avoid error through different environments
