Write Remove-StaleFile so it deletes files in the folder -Path whose LastWriteTime

is older than -Days days, and outputs the FileInfo of each file it deletes.

  - It must support -WhatIf and -Confirm: with -WhatIf nothing is deleted and

    nothing is output.

  - Only files directly in the folder (no recursion). Leave folders alone.

    Remove-StaleFile -Path ./logs -Days 30 -WhatIf

    # What if: Performing the operation "Delete stale file" on target "..."

        '[CmdletBinding(SupportsShouldProcess)] adds -WhatIf and -Confirm for you.'

        'Get-ChildItem -File returns only files. Compare $_.LastWriteTime with (Get-Date).AddDays(-$Days).'
