Add trailing newline to status reporting

[joswr1ght]

When spraying, MSOLSpray uses a Write-Host without a trailing LF to show incremental progress N of NNN users tested. Then the spray completes, there it no additional LF, so the prompt often looks like this:

PS /home/josh> Invoke-MSOLSpray -UserList ./userlist.txt -Password "Solarwinds123"
[*] There are 1 total users to spray.
[*] Now spraying Microsoft Online.
[*] Current date and time: 04/11/2022 10:53:45
PS /home/josh> sted

The sted is the trailing output of the status indicator. This patch adds a newline to the end of the main ForEach loop. The output at the end of MSOLSpray will look like this:

PS /home/josh> Invoke-MSOLSpray -UserList ./userlist.txt -Password "Solarwinds123"
[*] There are 1 total users to spray.
[*] Now spraying Microsoft Online.
[*] Current date and time: 04/11/2022 10:53:45
200 of 200 users tested
PS /home/josh> 

NBD, just a minor nicety. Thanks!
