V3: [ALL] can we use prettier to enforce consistent markdown formatting?

[efx]

the problem

The flexible nature of Markdown means each contributor will write it slightly differently. This creates a cognitive load on maintainers reviewing pull requests. I originally wanted to nudge users using editorconfig but discussing with @ErikSchierboom he mentioned prettier. Prettier is a JavaScript tool that automatically applies "opinionated formatting".

possible implementation approaches

• use prettier in a GitHub action to rewrite staged markdown file changes
• use prettier as a linter

alternatives

• editorconfig #863, #1150

How would you feel about doing this? Do thumbs up or down to vote. And certainly chime in with discussion to cover other angles or share some experience.

Discussion of #863 should continue in a single issue rather than being split amongst multiple issues.

[ErikSchierboom]

Agreed. I missed the other issue.

Thank you!
