{verb}-AzAvailabilityGroupListener needs to be rename to {verb}-AzSqlVMAvailabilityGroupListener

## Description

Below cmdlets should be rename and use SqlVM as prefix. Otherwise, it's hard to map its module.
Get-AzAvailabilityGroupListener
New-AzAvailabilityGroupListener
Update-AzAvailabilityGroupListener
Remove-AzAvailabilityGroupListener

## Steps to reproduce

```powershell

```

## Environment data

```

```

## Module versions

```powershell

```

## Debug output

```

```

## Error output

```

```

Start by locating the definitions and references for Get-AzAvailabilityGroupListener, New-AzAvailabilityGroupListener, Update-AzAvailabilityGroupListener, and Remove-AzAvailabilityGroupListener. Check how cmdlet names are mapped and where their documentation or tests are referenced; done means all four consistently use the AzSqlVMAvailabilityGroupListener prefix.
