Add `cli-progress` (Progress Bar) for CLI

[ovflowd]

This issue details the introduction of a progress bar to show the progress made in parsing and generating files. Similar to how we did on nodejs.dev (https://github.com/nodejs/nodejs.dev/blob/e670ec88c82119ed3141d97e24a2e98630a304c9/util-node/getApiDocsData.js#L25)

It should represent where it is and what it is generating/parsing. It should reside as a tool within src/utils and be imported within the cli.mjs
