SUGGESTION: Move volta config to .voltarc or somewhere else.

[zihluwang]

I think writing the toolchains configuration of a project in $PROJECT_DIR/.voltarc or somewhere else is better than writing them to package.json.

All nodes except volta in package.json is available to all users who have nodejs installed, but the node volta is only available to users installed Volta on their machines.

If someone don't know what Volta is and removes the volta node in package.json, the configuration will be disabled and cause errors due to environments.

Hi @zihluwang, thanks for the suggestion! We're tracking that in #282 currently, so follow that issue for updates. Right now, the main issue is that we need a design for the behavior that handles edge / corner cases (likely via an RFC).
