API: Use message-per-value for apihelp-query+tags-param-prop

Use message-per-value for message
apihelp-query+tags-param-prop to allow smaller strings
for translation.
Each prop in a message also will show up a new parameter on the help
page without the adjust of the translation (but than in english instead
of fully skip it).
