WIP: Add cookie banner

[kr8n3r]

What

Implement a configurable cookie banner based on the GOV.UK Design system cookie banner component

How to test

• run locally
• experiment with configuration options (example config)

To do:

• conditionally show different parts of the cookie banner based on config
• document configuration
• add tests

Thanks for working on this, Jani. Just got a couple of comments, hope they make sense!

I also noticed when running this locally and looking at the Design System frontend docs site that URLs seem to link directly to the first heading on a page, which means the cookie banner is automatically scrolled out of view. I'm not sure where that behaviour comes from, but I wonder what the reason was behind it and if it's something teams could turn off in the config (otherwise it's unlikely anyone will see the banner) ?

it looks like it's driven by in-page-navigation.js I don't think there's a config setting for this

https://docs.cloud.service.gov.uk/ imports a markdown file for the first page and that somehow circumvents the JS

Build is failing. See #230 for detail Fixed in #233

Hi @kr8n3r - thanks for working on this! Was it ready for another review or did you need to do more work on it? (I've added @lfdebrux as a reviewer for when it's ready.)

@jonathanglassman Are you ok to work with @kr8n3r on the related documentation PR? I'm happy to pre-i or 2i it.

it does require writing tests for it, but that would mean setting up a new test framework.
I worked on this when I had some time (which was a while ago) but it's not of any priority for us at the moment
