Documentation: Using markdown inside components with slots

[petedavisdev]

Feature request

Add instructions for using markdown inside components with slots.

What problem does this feature solve?

This is an awesome feature that deserves to be documented so that people know it's available and understand how to use it correctly.

What does the proposed API look like?

How should this be implemented in your opinion?

Add to documentation with:

• code examples for single slot and named slots with empty lines before and after markdown,
• warning about not using # shorthand for named slots.

Are you willing to work on this yourself?

Yes. PR on the way today :)
