Rename build.ralph to ralph.json

Initial assumption was that a custom file extension was required for the clients to narrow down the files to trigger file change events, but this is not the case.

Use .json so that that editor's default JSON support gets enabled.

Better to use a file name that is not tied to a specific file format.

Users can add file association instead.

In VSCode add the following to settings.json.

"files.associations": {
    "*.ralph": "json"
}

Hey @tdroxler, what do you think of this issue?

I'm not too sure. The rust link you shared here showed that they use rust-project.json.

I don't know 😕. If we use ralph.json now and also want to support ralph.toml in the future, we could. But with build.ralph we might be a bit more restricted to a single format, unless we do fancy parsing to detect format.

yeah I would favor ralph.json more, as you said:

Use .json so that that editor's default JSON support gets enabled.

is a big plus, editor usually come with a linter etc and we don't know for all editors if we can configure the same way as vscode.
