Created Unassigned: Bad example for Set-CertificateTemplate [102]

First example is incorrect. Should be:

```
PS C:\> Get-CertificateTemplate -Name WebServer | Get-CertificateTemplateACL | Add-CertificateTemplateAcl -User WebServerGroup -AccessType Allow -AccessMask Read, Enroll | Set-CertificateTemplateACL
```

Also, recommend adding example showing computer name, as it's non-obvious. For example:

```
PS C:\> Get-CertificateTemplate -Name WebServer | Get-CertificateTemplateACL | Add-CertificateTemplateAcl -User ServerName$ -AccessType Allow -AccessMask Read, Enroll | Set-CertificateTemplateACL
```
