oclif readme command doesn't work

When trying to auto-generate the README using oclif-dev, I ran into an issue: ..

SyntaxError: Unexpected token '.'

Because it is no longer supported, I have removed the oclif-dev dependency from package.json. In SCRIPTS, you should be able to generate the readme with:

oclif readme

(and oclif manifest in the prepack step)

However, it looks like there's a bug in the @oclif/core module.

twilio-labs / plugin-token
