[Typo] schedulder -> scheduler

[Spico197]

Describe the question.

A typo is found when loading and saving scheduler states:

InternEvo/internlm/utils/model_checkpoint.py

Line 857 in be32910

scheduler_states = llm_load(os.path.join(ckpt_path, "schedulder.pt"))

Maybe it's a better option to aggregate all constant variables into a single module and modify the file directly for global change?
