refactor: random config file cleanup

[kanadgupta]

🧰 Changes

Doing a little mess-around in this repo and refactored a few config files (some are a bit new and opinionated so feel free to push back on any of this)

• 5b70e53 Removed the .npmignore files — these are no longer needed since we use the files option (you can confirm this by running npm pack and looking at the file list in any of the subpackages)
• f4d0b92 added a prelint step — it feels a bit counterintuitive that we need to build the dist before we lint, so I figured this made sense.
• 91cacfd cleaned up the .prettierignore file — as of Prettier 3.0, files in the .gitignore are ignored by default: https://prettier.io/blog/2023/07/05/3.0.0.html#cli
• afc5fd8 removed the .eslintignore files in favor of the --ignore-path CLI option — this is somewhat opinionated but I generally like being able to consolidate config file options when possible

🧬 QA & Testing

To confirm the npmignore changes, you can confirm this by running npm pack and looking at the file list in any of the subpackages. And if the linting step passes, the Prettier/ESLint config file changes should be safe.
