Rule to warn against having a semicolon at the end of the line

[TylerLeonhardt]

function foo {
    $a = 1 + $b; # semicolon not needed
}

Install-Module Polaris; $a = 1 + $b; # semicolon needed after install-module, not needed after addition

We should warn against using semicolons at the end of a line.

I actually put semicolons at the end of a line by design so that I can safely copy-paste the script into any console host (I use ConEmu as a console host, I do not use the one by powershell or pwsh directly)

This rule would help enforce this PoshCode style guideline:
