Blocks landing page: Code contains highlight

[alexstine]

From: #245

It can be extremely verbose for screen reader users to hear highlighting marks in code samples/snippets. Possible fixes:

1. Remove the marks.
2. Add some type of raw view.
3. Add a copy button.

Heading 2: Complete creative control

Remove the marks.

We have a planned update to the example code cc @annezazu. This will be updated next week and will resolve this. The code will be updated to this:

registerBlockType( 'your-first-block/hello-world', {
    edit: function () {
        return <p>Hello world (from the editor)</p>;
    },
    save: function () {
        return <p>Hello world (from the frontend)</p>;
    },
} );

Add a copy button.

This page was built in the Editor so this is just the Code block, but more improvements could be tackled in future iterations.

@ryelle this issue can be closed now that the updated code example has been added to the page.
