Add support for --json to match ruby codeownership cli

[technicalpickles]

Currently, https://github.com/rubyatscale/code-ownership-vscode uses bin/codeownership to check the ownership to display. I was making some other changes, and thought maybe we could be using --json. We don't have that yet.

As an aside, it seems like that looking up a single for-file is about the same as gv, which is interesting. I was thinking about if there's an opportunity to make this an LSP? Or maybe just a long lived client/server so there isn't up front lookup cost.

@perryqh I see that this PR is old at this point and might be outdated, but Adding this functionality would be great. I would like to get https://github.com/rubyatscale/code-ownership-vscode working without the Ruby CodeOwnership gem and just directly calling this library and one of the differences (besides for_file vs for-file) is that this library doesn't support the --json flag. Are there any plans to land this functionality?

Good to know @pbomb! We can definitely add --json support!
