Update: allow empty string toml config

Fixes: #7371

Hi! team 👋
Currently, loadConfig module early returns null when configuration file is an empty string. However, some files such as .toml and .yaml allow an empty string file, so loadConfig should not early return null when the config file is an empty string.

I fixed this behavior to parse also empty string files (, and a file parser throws an error when a file parser such as JSON does not allow empty string).

💻 Examples

with empty json

🚨 Test instructions

• parse a valid JSON config file
• loadConfig should throw an error with the invalid empty string JSON
• loadConfig can load a valid empty string toml
