Update PowerShell code not conforming to style guide

[schrolla]

💡 Summary

Update existing PowerShell code to apply project rules of style more consistently. While automation checks for many of the rules we have, some are not. In particular, not all powershell includes docstrings for defined functions that allows developers to easily understand what a function does and use Get-Help to bring up function documentation.

Motivation and context

Improved readability and maintainability of the ScubaGear PowerShell code base.

Implementation notes

Please provide details for implementation, such as:

• Check Posh style guide for style gaps not checked by linter already
• Review existing Powershell code to ensure all functions have docstrings with synopsis at a minimum
• Review PowerShell code for other style gaps
• Note gaps for potential inclusion in linter for the future

Acceptance criteria

How do we know when this work is done?

• All PowerShell code has been successfully reviewed for adherence to style guide
• Any deviations from style guide have been corrected or exempted
• Open issues to add style gaps to linter in the future

Check to see if existing linters have support to monitor for additional gaps. Look at PSSA MissingCommentHelp rule.
