doc: Use self-closing tags for `return` and `argument`

For the time being we don't support writing a description for those, preferring
having all details in the method's description.

Using self-closing tags saves half the lines, and prevents contributors from
thinking that they should write the argument or return documentation there.

 				Appends a [PackedVector2Array] that contains the vertices of an outline to the internal array that contains all the outlines. You have to call [method make_polygons_from_outlines] in order for this array to be converted to polygons that the engine will use.

 			<description>
 				Adds a [PackedVector2Array] that contains the vertices of an outline to the internal array that contains all the outlines at a fixed position. You have to call [method make_polygons_from_outlines] in order for this array to be converted to polygons that the engine will use.
