fix: Improve error handling in mkdir function (logseq#9247)

* Improve error handling in `mkdir-if-not-exists` function
This PR improves the error handling in the `mkdir-if-not-exists` function by logging the "EEXIST" error (which indicates the directory already exists) instead of throwing it. Other errors will continue to be handled as before.
- [x] closes logseq#9182

* enhance: move error handling to fs/node.js

* fix: make EEXIST silent and only throw other errors
