Add missing GGUF quantization types (TQ1_0, TQ2_0, MXFP4) & move legacy types to the bottom (#2191)
* Add missing GGUF quantization types (TQ1_0, TQ2_0, MXFP4)
Sync the quantization types table with the source of truth at
huggingface.js/packages/gguf/src/quant-descriptions.ts:
- Add TQ1_0 and TQ2_0 (ternary quantization)
- Add MXFP4 (4-bit Microscaling Block Floating Point)
- Fix missing period on Q8_1 description
* Move legacy quantization types to bottom of table
Reorganize the table to place legacy types (Q8_0, Q8_1, Q5_0, Q5_1,
Q4_0, Q4_1) at the bottom with a separator row for better clarity.
