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>
 				Returns [code]true[/code] if the given event is part of an existing action. This method ignores keyboard modifiers if the given [InputEvent] is not pressed (for proper release detection). See [method action_has_event] if you don't want this behavior.
 				If [code]exact_match[/code] is [code]false[/code], it ignores the input modifiers for [InputEventKey] and [InputEventMouseButton] events, and the direction for [InputEventJoypadMotion] events.
