[Feature Request]: Move PS scripts from `.github\actions` to `utilities` to have both triggers (gh + ado) on the `*.yml` extension

[eriqua]

Description

PS scripts leveraged by actions and pipelines should be in the utilities folder.

Some gh actions don't follow this approach (e.g. .github\actions\templates\getWorkflowInput\scripts\Get-WorkflowDefaultInput.ps1)

Moving PS scripts from .github\actions to utilities would allow more consistency between gh and ado module pipeline triggers:

• ADO: '/.azuredevops/pipelineTemplates/*.yml'
• GH: '.github/actions/templates/*.yml' (currently '.github/actions/templates/**')

Steps for this issue:

• Move PS scripts from .github\actions to utilities
• Align GH triggers from '.github/actions/templates/**' to '.github/actions/templates/*.yml'
