Assembly Scanning - AddActivitiesFrom method missing

The method/overload for adding activities from assemblies dynamically mentioned in [this ](https://docs.elsaworkflows.io/extensibility/custom-activities?q=Assembly+Scanning#register-activities-with-assembly-scanning)section of the documentation doesn't seem to exist:

```
builder.Services.AddElsa(elsa =>
{
// Get all assemblies in the current domain
var assemblies = AppDomain.CurrentDomain.GetAssemblies()
.Where(a => a.FullName.StartsWith("MyCompany."));

foreach (var assembly in assemblies)
{
elsa.AddActivitiesFrom(assembly); <-- this overload doesn't exist
}
});
```
The `Elsa.Extensions.ModuleExtensions` class in `Elsa.Workflows.Management `only contains this signature: `AddActivitiesFrom(this IModule module)`

No overload taking an `Assembly`

Are the docs outdated or am I missing an refference?
