Fix warning message json-format suggestion to proper syntax

The warning message appears for example as "Use --json to see the list
of exports TypeScript can see but Node.js cannot." However, passing
`--json` leads to an error: `error: unknown option '--json'`

Per `--help` argument definition, the correct syntax is `-f json` or
`--format json`, which I confirmed both worked for me.
