Update GGUF docs

• Use the same tensor types in ggml.h

  ggml/include/ggml/ggml.h

  Lines 342 to 374 in 4afed64

  	enum ggml_type {
  	GGML_TYPE_F32 = 0,
  	GGML_TYPE_F16 = 1,
  	GGML_TYPE_Q4_0 = 2,
  	GGML_TYPE_Q4_1 = 3,
  	// GGML_TYPE_Q4_2 = 4, support has been removed
  	// GGML_TYPE_Q4_3 = 5, support has been removed
  	GGML_TYPE_Q5_0 = 6,
  	GGML_TYPE_Q5_1 = 7,
  	GGML_TYPE_Q8_0 = 8,
  	GGML_TYPE_Q8_1 = 9,
  	GGML_TYPE_Q2_K = 10,
  	GGML_TYPE_Q3_K = 11,
  	GGML_TYPE_Q4_K = 12,
  	GGML_TYPE_Q5_K = 13,
  	GGML_TYPE_Q6_K = 14,
  	GGML_TYPE_Q8_K = 15,
  	GGML_TYPE_IQ2_XXS = 16,
  	GGML_TYPE_IQ2_XS = 17,
  	GGML_TYPE_IQ3_XXS = 18,
  	GGML_TYPE_IQ1_S = 19,
  	GGML_TYPE_IQ4_NL = 20,
  	GGML_TYPE_IQ3_S = 21,
  	GGML_TYPE_IQ2_S = 22,
  	GGML_TYPE_IQ4_XS = 23,
  	GGML_TYPE_I8 = 24,
  	GGML_TYPE_I16 = 25,
  	GGML_TYPE_I32 = 26,
  	GGML_TYPE_I64 = 27,
  	GGML_TYPE_F64 = 28,
  	GGML_TYPE_IQ1_M = 29,
  	GGML_TYPE_COUNT,
  	};

I think this change breaks the value of GGML_TYPE_I8 (16 -> 24), GGML_TYPE_I16 (17 -> 25), and GGML_TYPE_I32 (18 -> 26).
