[PowerShell][Hubs] Remove-FinOpsHub fails when there's only one resource

[flanakin]

🐛 Problem

Remove-FinOpsHub fails when there's only one resource:

Method invocation failed because [System.Boolean] does not contain a method named 'Reduce'

👣 Repro steps

1. Create a hub
2. Manually delete all resources except for the Data Factory
3. Run Remove-FinOpsHub command

🤔 Expected

Should return true when successful.

ℹ️ Additional context

Error is on line 101 of Remove-FinOpsHub.ps1:

return ($resources | Remove-AzResource -Force:$Force).Reduce({ $args[0] -and $args[1] }, $true)

The fix is to force the $resources | Remove-AzResource into an array. We should also be able to simplify and remove the Reduce() method.

return -not (@($resources | Remove-AzResource -Force:$Force) -contains $false)
