fix: rename LOGLEVEL to LOG_LEVEL

[liuhuo23]

I found that when I used debug! to print logs, it always had no output. Eventually, I discovered that in the .envrc file it was LOG_LEVEL while in the code it was LOGLEVEL.

I would prefer the other way around and use LOG_LEVEL and update the code accordingly. I think it is more conventional, what do you think?

[liuhuo23]

yes， should use LOG_LEVEL

[orhun]

want to make the change in the PR? 🙂
