feat(rome_cli): Add a new option --config-path to set the path to rome.json

[realtimetodie]

Adds a new option --config-path to set the filesystem path to the directory of the rome.json configuration file.

Example

$ rome check --config-path=../../../example

The --config option appends a base path to the rome.json configuration file path

../../../example/rome.json

Error handling

If the user explicitly sets a path to the rome.json configuration file using the --config-path option and the file is not found, an error will be thrown.

Example

$ rome check --config-path=/test.json

Error message

...
× Rome couldn't read the following file, maybe for permissions reasons or it doesn't exists: /test.json/rome.json

[ematipico]

Thank you for this PR! I think we should rename the option, for example --config-path. This would be in line with --file-path

[realtimetodie]

@ematipico Yes, I like this idea. I renamed the option to --config-path and updated the documentation.

Have you tried running the CLI using windows like style paths? E.g. --config-path=..\foo\rome.json

Does it work?

Have you tried running the CLI using windows like style paths? E.g. --config-path=..\foo\rome.json

The dot notation is covered by the DOS specification

assert_eq!(Path::new("..\\..").join("rome.json"), PathBuf::from("..\\..\\rome.json"));

@realtimetodie could you please tick the checkbox of The PR requires documentation? We would need to update the website with this new argument

[realtimetodie]

@ematipico Yes, I will take care of the documentation.
