Pardon me if this is a stupid question:
I am wondering where can I find the dependency requirements for LightGBM Python package, especially for a specific version. E.g. I found a pyproject.toml (https://github.com/microsoft/LightGBM/blob/master/python-package/pyproject.toml) under the master branch. But such file does not exist for a specific version (e.g. if I switch to Tag v3.3.3, this file does not exist).

How do I know the dependency requirement for a specific version?
