Minor bug in N-Triples/N-Quads EBNF

Hello all,

Production 6 of the N-Triples [1] grammar and production 7 of the N-Quads [2] grammar include '@' LANGTAG. The terminal LANGTAG also begins with '@'. Thus, specifying a language would require two @, making the examples in Sec 2.3 [3] of the N-Triples document invalid N-Triples / N-Quads. Furthermore, this also means that a valid N-Triples document containing language tags would not be valid Turtle document. The '@' sign in these two productions should be removed to bring them in line with production 128s of Turtle [4].
