feat: add plainText to headings

[benjaminrobinet]

What does it do?

It allows to have access to the plainText of a heading block.

Why is it needed?

Sometimes you might want to have access to the plain text of a heading to be able to add an attribute to it, like for creating anchors to point to them.

How to test it?

In a frontend app, use the renderer (link it via yarn), and pass a custom component for heading that uses the plainText prop

The changes look good! I think there are just a couple places you'll need to update:

• the types:

  blocks-react-renderer/src/BlocksRenderer.tsx

  Line 91 in 4c6faf1

  plainText?: T extends { type: 'code' } ? string : never;

• the readme: https://github.com/strapi/blocks-react-renderer/blob/4c6faf1d62f5c513545e4150e1b02170660c289e/README.md#custom-components

I'm gonna push a fix for that today !
Was thinking if it wouldn't be interesting to also pass the raw object (from the strapi response) to every block types. For now, we only have access to the React.Node
