Search in parent folders for commit.json config file

[alt-art]

The current implementation only searches the config file in pwd, home folder and argument, But git and other tools as the capability of searching config files and folders in parent folders in case someone move out of the config file folder.

Note: This will need a depth value for stop at a given iteration

Function that will handle this:

commit/src/config/mod.rs

Lines 81 to 92 in ac7cfe0

	fn get_config_path() -> Result<PathBuf> {
	let current_dir = std::env::current_dir()?;
	let current_file = current_dir.join("commit.json");
	if current_file.is_file() {
	Ok(current_file)
	} else {
	let config_file = dirs::config_dir()
	.ok_or_else(|| anyhow!("Could not find config directory"))?
	.join("commit/commit.json");
	Ok(config_file)
	}
	}
