Add documentation on Terraform recipe providers configuration

[kachawla]

What content needs to be created or modified?

Terraform recipe tab in https://docs.radapp.io/guides/recipes/howto-author-recipes/

Describe the solution you'd like

For Terraform recipes Radius uses required_providers block from Terraform module to determine if configuration for AWS/Azure should be added. However this is not a requirement enforced by Terraform so we should explicitly document this requirement for specific providers to be configured by Radius.

This issue in the Radius repo has more context on the confusion caused by this: radius-project/radius#7109

Where should the new material be placed?

Terraform recipe tab in https://docs.radapp.io/guides/recipes/howto-author-recipes/

Not a PR, but we have an open issue: radius-project/radius#7109
