	doc: restore class documentation for Struct

	* struct.c: restore class documentation for Struct
	  that disappeared with r46663.

	Due to r46663, the class documentation for Struct disappeared.
	(The revision inserted the definition of `InitVM_Struct` between
	the rdoc and the definition of `Init_Struct`.)

	The docs are rendered for 2.1: <https://docs.ruby-lang.org/en/2.1.0/Struct.html>,
	but not for later versions, see: <https://docs.ruby-lang.org/en/2.2.0/Struct.html>
	(Same for `ri` pages).

	[ruby-core:79416] [Bug #13189]
