[Doc]: Remove-AzSynapseWorkspacePackage

### Type of issue

Code doesn't work

### Feedback

Via DevOps we run a pipeline that removes existing synapse workspace packages and upload the artifacts that we have in our devops-enviroment. This is done by using the Remove-AzSynapseWorkspacePackage

**While using the Remove-AzSynapseWorkspacePackage, an error occurs with the message:**
```
Remove-AzSynapseWorkspacePackage : Array cannot be null.
Parameter name: bytes
```

**This is the code we use:**
```
Write-Host "Updating packages on workspace $($ws.Name)"
$workspacePackages | ForEach-Object { Write-Host " - Package to delete: $($_.Name)" }
$workspacePackages | ForEach-Object {
Write-Verbose -Message "Deleting package: $($_.Name)" -Verbose
Remove-AzSynapseWorkspacePackage -Name $_.Name -WorkspaceName $workspaceName -Force -Verbose
}
```

We already determined that there are packages that need to be removed. When entering the Remove-AzSynapseWorkspacePackage command, the named packed is still there and not null. During the command the package gets removed, but ends up showing this message.

Start with src/Synapse/Synapse/help/Remove-AzSynapseWorkspacePackage.md and reproduce the reported command against a Synapse workspace containing removable packages. Trace the cmdlet implementation from its documented entry point to identify why successful deletion still reports the null-bytes error. Done means the package is removed without the reported error and the relevant documentation remains accurate.
