Improving Fastify's CLI (Node.js Framework) (Open Source Contributions)

Added a few features to Fastify's CLI tool, which provides command line tools to generate, write, and run an application with one single command.

A summary of my contributions can be described as follows:

- Add support for configuration file to pass server options along with command line options.

- Add support for exporting server options using on ESM.

- Add the capability to generate ESM based templates, (CommonJS was the only supported format)

- Improve the markdown linter for the allowed ecosystem packages (Module name validation + alphabetical ordering)
