Update AzureRM Provider to 3.45.0+ for `auth_provider_v2` intellisense

I recently created an issue on github with some bad example code which is a situation I might have avoided if the terraform resource I was using was known the the VS Code Terraform Extension. In particular, the `auth_settings_v2` block, which is recommended for use over `auth_settings` by Microsoft as it implements a newer Az API for certain things. I think `auth_settings_v2` came around in 3.45.0, so the extension is only a little behind. Maybe I'm too-early an adopter.

At time of writing, latest azurerm provider is 3.47.0. Extension currently uses 3.44.0. Please update!


Start by locating where the extension pins or obtains the AzureRM provider version and where provider resource intellisense is sourced. Update the supported version to 3.45.0 or later, then verify that the auth_settings_v2 block is recognized by the VS Code Terraform Extension.
