DateTime Properties Are Not Localized

The confirmation for activated roles displays the `StartDateTime` and `EndDateTime` properties as UTC instead of local time. This makes it unclear what the actual start/end time is.

```PowerShell
PS > Get-Date; Get-Date -AsUTC

Wednesday, July 27, 2022 1:23:00 PM
Wednesday, July 27, 2022 5:23:00 PM

PS > Enable-ADRole 'Global Reader (LJnv8vs6uUa3z6Em7nTEUZY-Uygeo0pJj_wBT3Lkhj8-1-e)' -Justification 'foo' -Hours 1

Action Status PrincipalDisplayName RoleName Scope StartDateTime EndDateTime
------ ------ -------------------- -------- ----- ------------- -----------
selfActivate Provisioned bmkaiser Global Reader Directory 7/27/2022 5:23:30 PM 7/27/2022 6:23:00 PM
```

Start by reproducing the `Enable-ADRole ... -Justification 'foo' -Hours 1` command and comparing its confirmation output with `Get-Date` and `Get-Date -AsUTC`. Trace how the confirmation formats `StartDateTime` and `EndDateTime`; done when both values display in local time rather than UTC.
