Insufficient Documentation to use the Cmdlet

### Type of issue

Missing information

### Feedback

The documentation and examples for the `Remove-AzConfigurationAssignment` cmdlet are completely insufficient to actually use the cmdlet in automation. Please provide better examples so that your customers can use this cmdlet. Examples of what we need are below.

`-ResourceType`: We have tried every combination we can think of for this parameter. What are valid values for this?

`-ProviderName`: Is this `Microsoft.Compute` or `Microsoft.Maintenance`?

`-ConfigurationAssignmentName`: Where is this found? based on a Az Graph Query, there is a name populated with some random characters. We assume this is the name, but not clear.

`-ResourceName`: Where to find this and how does it differ from `-ConfigurationAssignmentName`?

`-ResourceParentType`: What is this and what are the possible values?

`-ResourceParentName`: Where to find this?

We have tried many combinations over and over again, but are frequently hit with errors like this that are too vague to know how to fix it:

```Body:
{
"Error": {
"Code": "InvalidResource",
"Message": "Invalid configurationAssignment"
}
}
```

Start with src/Maintenance/Maintenance/help/Remove-AzConfigurationAssignment.md and compare it with the published cmdlet page. Investigate the six questioned parameters and the InvalidResource example, then update the documentation with valid values, how to locate each name, and automation examples that make successful usage and error resolution clear.
