DXCDT-537: Removing minor validation to enable easier importing of auth0_guardian

[willvedd]

🔧 Changes

When importing auth0_guardian with a config-driven import, it is possible that generated configuration be invalid. In particular if the phone block is disabled or not defined. The result is this error:

with auth0_guardian.guardian,
│   on auth0_generated.tf line 18, in resource "auth0_guardian" "guardian":
│   18:     message_types = []
│
│ "phone.0.message_types": all of phone.0.message_types,phone.0.provider must be specified

We investigated this issue pretty thoroughly and there is not a simple way of addressing in a more idiomatic way, through the flattens or expands. This is made more difficult by the Management API which can return empty phone providers and empty-set message types.

An important note – in practical terms, it would be rare to configure the message types without a provider but it is technically possible because they are administered with separate endpoints. Because of this, this validation is lax but still correct.
