Update AzureRM Provider to 3.45.0+ for `auth_provider_v2` intellisense

[ncook-hxgn]

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!
