Install the latest version of twilio-run for new projects

[dkundel]

Should we change for SIGNAL that we always grab the latest version of twilio-run instead? That way we don't have to release a new version of this for everything. We can still use a semver range like 2.* instead of a full latest but that way we still don't have to do re-releases
