Update src/submission/check_validity.py

Hello!

This is a small fix for correct model parameter size.
Because of the regex `r"(\d\.)?\d+(b|m)"`, sometimes it returns wrong model size if it tries to extract model size from its name.

For example, `Sao10K/Frostwind-10.7B-v1` currently has 0.7 param size in the leaderboard, which is wrong.

I hope this improves leaderboard accuracy a bit!

Cheers
