Change FilterOutCommonParams to global

[HeyItsGilbert]

Minor tweak to FilterOutCommonParams to be global.

Description

Pester isn't picking up the script level function. The global function should resolve that.

Related Issue

#26

Motivation and Context

This well let Pester 5 find it.

How Has This Been Tested?

This test is included on the repo so I'm hoping the CI on the PR will validate it.
I use it currently for https://github.com/HeyItsGilbert/RPGDice/blob/main/tests/Help.tests.ps1#L5

I built @HeyItsGilbert fork of Stucco then build a test module from that and the tests were all passing on the newly scaffolded module so it would appear the scope of the FilterOutCommonParams is the issue here.

Cheers for this Gilbert 🎉
