[New Feature]: YamlCreate.ps1 should work with PowerShell StrictMode

### Description of the new feature/enhancement

PowerShell "Strict Mode" is a way to have PowerShell help you write better scripts, by complaining when your scripts violate best-practice coding rules. It helps you find bugs you may not even realize you had. See: [Set-StrictMode](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/set-strictmode?view=powershell-7.5). According to Strict Mode, `YamlCreate.ps1` could use some improvement.

In addition to just making `YamlCreate.ps1` better, this means it won't fail for zealots like me, who set `Set-StrictMode -Version Latest` in their `$profile` script. :D

## Repro steps:
1. `Set-StrictMode -Version Latest`
2. `.\Tools\YamlCreate.ps1`

## Expected Result:
It all just works, and looks good doing it.

## Actual result:
TONS of red error spew:

### Proposed technical implementation details (optional)

_No response_

Start with Tools/YamlCreate.ps1 and reproduce the reported failures after running Set-StrictMode -Version Latest. Trace the errors at the listed lines, then rerun the script to confirm it completes without StrictMode errors and reaches its normal prompt.
