What is the issue?

Set-ItResult prepends a redundant "because" and appends a comma to the end of the -Because in the exception message.

Expected Behavior

Set-ItResult, when given a -Because message, should append that to the result type message

ex:

try {
    Set-ItResult -Skipped -Because "we are forcing it to skip"
} catch {
    $_.Exception.Message
}

Expected:

is skipped, because we are forcing it to skip

Actual:

is skipped, because  because we are forcing it to skip,

Steps To Reproduce

try {
    Set-ItResult -Skipped -Because "we are forcing it to skip"
} catch {
    $_.Exception.Message
}

Describe your environment

Pester version : 5.6.1 C:\Users\Tyler\Documents\PowerShell\Modules\Pester\5.6.1\Pester.psm1
PowerShell version : 7.4.6
OS version : Microsoft Windows NT 10.0.19045.0

Possible Solution?

This should be a simple change to the formatting for the Because message in the Set-ItResult function to remove the redundant "because" and strip the trailing comma.

I have the changes up in a fork now and will be submitting a PR shortly.
