The property "location" does not exist in the resource definition for 'Microsoft.Web/sites/basicPublishingCredentialsPolicies@2021-03-01'

**Bicep version**
Bicep CLI version 0.7.4 (5afc312467)
**Describe the bug**
The property "location" does not exist in the resource definition for 'Microsoft.Web/sites/basicPublishingCredentialsPolicies@2021-03-01'

**To Reproduce**
Running the following command doesn't work:

```powershell
new-azresourcegroupdeployment -Name functionApp -TemplateFile C:\scrap\functionApp\template.bicep -ResourceGroupName test-rg
```

With this bicep resource:

```bicep
resource sites_name_scm 'Microsoft.Web/sites/basicPublishingCredentialsPolicies@2021-03-01' = {
parent: sites_name_resource
name: 'scm'
properties: {
allow: true
}
}
```

Here is the error message:

```
New-AzResourceGroupDeployment: 11:38:25 - The deployment 'functionApp' failed with error(s). Showing 2 out of 2 error(s).
Status Message: The parameter location has an invalid value. (Code: BadRequest)
- The parameter location has an invalid value. (Code:)
- (Code:BadRequest)
- (Code:)
```

If I correct the resource with the location property:

```bicep
resource sites_name_ftp 'Microsoft.Web/sites/basicPublishingCredentialsPolicies@2021-03-01' = {
parent: sites_name_resource
location: location
name: 'ftp'
properties: {
allow: true
}
}
```

I get the warning that the location property does not exist in the resource definition but the deployment works fine:

```
new-azresourcegroupdeployment -Name functionApp -TemplateFile C:\scrap\functionApp\template.bicep -ResourceGroupName test-rg

Start by reproducing the deployment with Bicep CLI 0.7.4 and the Microsoft.Web/sites/basicPublishingCredentialsPolicies@2021-03-01 resource shown in the issue. Trace how this resource type handles location during validation and deployment; done means the definition and deployment behavior agree without requiring an undocumented location property or producing an invalid-location error.
