fix: split .INPUTS/.OUTPUTS type and description onto separate lines

PlatyPS renders each .INPUTS/.OUTPUTS line as a ### heading. The canonical
PowerShell format puts the type name alone on its first line and the
description as body text on the next line. This prevents MD026
(no-trailing-punctuation) violations in generated docs.

Correct format:
  .OUTPUTS
  System.String
      A greeting string for the given name.
