[DOCS] Provide best practices, tips, etc. on the contributing guidelines

[Panquesito7]

Description

It'd be awesome if we could add best practices, tips, filename guidelines, and other stuff (like seen in other repositories such as C, C++, and TypeScript).
This issue is open for Hacktoberfest! Feel free to contribute and make a PR. 🚀
