[AVM Module Issue]: Improve Support for OpenTofu by updating AVM module versions to versions that allow for v1.9.1 to be used

### Check for previous/existing GitHub issues - [x] I have checked for previous/existing GitHub issues ### Issue Type? Feature Request ### (Optional) Module Version _No response_ ### (Optional) Correlation Id _No response_ ### Description The following AVM module called by this module have version constraints that are incompatible with OpenTofu: Azure/avm-res-network-virtualnetwork/azurerm It contains the version constraint: ``` terraform { required_version = ">= 1.9.2" .... } ``` The latest version of OpenTofu is 1.9.1, which doesn't meet this requirement. Later versions of the above module use the version constraint: ``` terraform { required_version = ">= 1.9, < 2.0" .... } ``` Which should be compatible with OpenTofu. I know that OpenTofu is not officially supported, but it would be great if the module versions could be upgraded to enable it. I'm happy to get a PR in if that is something you are open to?
