Description

fastify generate doesn't seem to work well when multiple options are provided. fastify generate . --esm & fastify generate . --lang=ts both seem to work well. But, combining options fastify generate . --esm --lang=ts doesn't seem to create esm support in the generated ts project.

Steps to Reproduce

mkdir foo && cd foo && fastify generate . --esm --lang=ts

Expected Behavior

The expected behavior is to generate an esm enabled typescript project
