Migrate Tokenizer Components to utilize pytorch-labs/tokenizers

[Jack-Khuu]

🚀 The feature, motivation and pitch

@larryliu0820 has created a new shared repository for hosting tokenizer definitions.

The initial migration attempt was reverted in #1414 due to a tokenizer issue flagged in #1413, but should be straightforward to debug and reland

Task: Taking inspiration from #1401, reattempt this migration
