Standardize builtin function parameters

[michaeltlombardi]

Description

• Builtin functions Get-Plugin and Get-Role use the non-standard parameters plugin and ole respectively where they should use ame as is normal in PowerShell functions. This commit updates those functions and their comment based help to reflect the correct parameters.
• This is a breaking change if people are relying on the old parameters.
