ci: support python310 tomli

[Jay-ju]

Python 3.11 and later versions natively support tomllib, but lower versions require third-party libraries like tomli or toml.
For example:

# Python 3.11+ (built-in)
import tomllib

# For Python <3.11:
# First install: pip install tomli
import tomli as tomllib
