Description

The keyvault_access_policies_azuread_apps currently references the incorrect config key and the azure_devops template is configured at the incorrect level.

Does this introduce a breaking change

• YES
• NO

Testing

Running terraform plan should now produce no errors and the apply should now run without error.

Apologies for the closed PR, my fancy git config working against me!

@arnaudlh I'm not sure if the level change was on purpose to account for something else, but these two changes seemed to fix the error in the spirit of your most recent changes.
