Share AI prompts to make the creation of draft patterns easier

Some of our contributors struggle with the first steps of creating a draft pattern. By providing AI prompts for this step we can make it easier for these contributors to create an initial draft version very quickly, which they can take and adapt.

This idea stems from this conversation:

... do we want to create some prompts for Cursor & VSCode that will help people build patterns?

If you haven’t used them yet, here’s some background & fodder.

https://docs.cursor.com/context/rules

https://code.visualstudio.com/docs/copilot/copilot-customization#_prompt-files-experimental

https://github.com/PatrickJS/awesome-cursorrules

I’d be happy to start a PR with some and we can use them to build an initial version of this pattern.
