feat: VCS support

[ematipico]

Summary

Closes #2492

This PR adds an opt-in integration of Rome with a VCS.

The integration can be set via configuration of via CLI:

Configuration of rome.json:

{
	"vcs": {
		"enabled": true,
		"clientKind": "git",
		"useIgnoreFile": true
	}
}

CLI:

rome format --write --vcs-enabled=true --vcs-client-kind=git --vcs-use-ignore-file=true --vcs-root=.

The root option in an optional flag tells Rome where to look for VCS files. The root will work as follow:

If root is passed:

1. if rome.json is present, rome will append root to the configuration path to discover the VCS files;
2. if rome.json is not present, rome will append root to the working directory to discover the VCS files;
3. if rome.json is not present, and the working directory is not present, rome will use the current path to discover the VCS files;

If root is not passed:

1. if rome.json is present, rome will use the configuration path to discover the VCS files;
2. if rome.json is not present, rome will use the working directory to discover the VCS files;
3. if rome.json is not present, and the working directory is not present, rome will use the current path to discover the VCS files;

As for now, the only feature that this PR does add to Rome is the possibility of ignoring files via .gitignore file. Though, there's a limitation: in this PR, multiple .gitignore files are a non-goal, and the only ignore file that is read is the one present in the root We might add this functionality later when we feel the whole architecture behind it is stable.

Test Plan

Added test cases for format, check and ci commands.
