### Versions

**terraform**: 1.6.6

**azure provider**: v3.88.0

**module**: 5.0.3

### Description

When trying to add a `resourceSelector` to an existing policy assignment, terraform does not detect the change.

#### Describe the bug

I added an archetype_config_overrides to override the Deny-Resource-Locations to allow me to deploy static web apps in another region than the on whitelisted.

```hcl
archetype_config_overrides = {
landing-zones = {
archetype_id = "es_landing_zones"
resourceSelector = {
Deny-Resource-Locations = {
name = "Allow static web app"
selector = {
in = []
kind = "resourceType"
not_in = [
"Microsoft.Web/staticSites",
]
}
}
}
}
}
```

#### Additional context

I can update the parameter easily but not the resource selector.
