Allow me to pass an `.editorconfig` file path into `--config-path`

[flagbug]

Environments:

• CSharpier Version: 0.30.6
• Running CSharpier via: dotnet cli
• Operating System: All
• .csharpierrc Settings: any
• .editorconfig Settings: any

Steps to reproduce:
Run dotnet csharpier --config-path ./path/to/editorconfig .

Expected behavior:

CSharpier uses the editorconfig file for configuration. The documentation states

CSharpier has support for a configuration file. You can use any of the following files

A .csharpierrc file in JSON or YAML.
A .csharpierrc.json or .csharpierrc.yaml file.
A .editorconfig file. See EditorConfig section below.

which is why I assumed this would be working

Actual behavior:

CSharpier throws an error: Unhandled exception: (Line: 1, Col: 1, Idx: 0) - (Line: 14, Col: 16, Idx: 214): Exception during deserialization

Not sure if this is even intended to work, I just assumed from the documentation. Feel free to close the issue if this is not an expected behavior!

I think this was just an oversight on my part when adding .editorconfig support which came after --config-path was already an option. It makes sense to add support for it. Not as straightforward as I originally hoped but things almost never are!
