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.

 			<description>
 				Adds a point to the curve. For each side, if the [code]*_mode[/code] is [constant TANGENT_LINEAR], the [code]*_tangent[/code] angle (in degrees) uses the slope of the curve halfway to the adjacent point. Allows custom assignments to the [code]*_tangent[/code] angle if [code]*_mode[/code] is set to [constant TANGENT_FREE].
