Add Azure Key Vault settings source

[AndreuCodina]

Add Azure Key Vault settings source.

Doubt: Where should I add the required Python packages (azure-keyvault-secrets==4.8.0 and azure-identity==1.16.0) to use AzureKeyVaultSettingsSource?

This is the infrastructure:

resource "azurerm_resource_group" "pydantic" {
  name     = "pydantic"
  location = "northeurope"
}

resource "azurerm_key_vault" "pydantic" {
  name                          = "kv-pydantic"
  resource_group_name           = "pydantic"
  location                      = "northeurope"
  tenant_id                     = data.azuread_client_config.current.tenant_id
  sku_name                      = "standard"
  soft_delete_retention_days    = 7
  purge_protection_enabled      = false
  enable_rbac_authorization     = true
  public_network_access_enabled = true
}

resource "azurerm_key_vault_secret" "sql_server_password" {
  name         = "SqlServer--Password"
  value        = "SqlServerPassword"
  key_vault_id = azurerm_key_vault.pydantic.id
}

resource "azurerm_key_vault_secret" "my_password" {
  name         = "MyPassword"
  value        = "MyPassword"
  key_vault_id = azurerm_key_vault.pydantic.id
}

Closes #143

Thanks @AndreuCodina for this PR.

It has to be added to optional dependencies section

Also, I can't see any test added here. You need to add some tests

How do I make the imports in code? I've created the function import_azure_key_vault, but I'm getting mypy pydantic_settings pydantic_settings/sources.py:14: error: Cannot find implementation or library stub for module named "azure.core.credentials" [import-not-found]

You need to update the requirements by running make refresh-lockfiles command

$ make refresh-lockfiles

@AndreuCodina I changed the example in the doc and made it simpler.

Please add AzureKeyVaultSettingsSource to the init and then change the doc example to import AzureKeyVaultSettingsSource from pydantic_settings instead of pydantic_settings.sources

Done. I've removed "```python" in the markdown because if not, the tests fail.

it fails because of imports in the code. I've fixed it and returned the "```python"
