Provide a version flag

Pull Request

Summary

Provides a --version flag for the Resonate server, with the current version set in version.json. I'm open to other ways of setting this value, as long as it's in a file somewhere 😄 It could also potentially be set as a variable in flake.nix.

Changes

Adds a version.json file as the canonical place to set the version, adds a --version flag to the CLI, and updates the package definition in flake.nix to properly supply version information during the build process.

Related Issues

This is in response to #301, which is well intentioned but doesn't quite provide the right mechanism.

Testing

nix build
./result/bin/resonate --version
resonate version 0.5.0

Since we need the version in a file anyway we will just put the version in the root cobra command instead. Thanks.
