Failed to import format data file

[BernieWhite]

When importing PSDocs module, importing PSDocs.Format.ps1xml may fail if PSDocs.dll is blocked by Windows because it was downloaded from the PowerShell Gallery.

Import-Module : Errors occurred while loading the format data file:

We should add a note for troubleshooting this issue.

It can be fixed by using Unblock-File.

For example:

Get-ChildItem -Path 'C:\Program Files\WindowsPowerShell\Modules\PSDocs\' | Unblock-File;
