Extensions in parameters should be part of the description column instead of the name column

[jrossignol]

Description

Moved extensions from the last item in parameters-col_name to the last item of parameters-col_description (after examples)

Motivation and Context

Extension fields that are part of a schema show up on the right hand column, but extension fields on parameters are under the left hand column. This tends to result in extensions of even moderate length either wrapping or expanding the name column unnecessarily. It would be more consistent (and cleaner) to have those extensions appear under the description.

How Has This Been Tested?

Built the change and visually verified with & without other fields (such as example & examples)
