Add mission patch page

[edwardhorsford]

Adds a general page to show off the mission patches that teams have made.

This is mostly a copy of the existing DfE Mission patch page.

To start with, I've copied over the 3 existing Mavis mission patches (and optimised the png's).

Some notes:

• The repo has some annoying default styling by default for figures, and I've added a custom class to override this.

Adding more mission patches:

• Images should be square, transparent pngs that have been optimised. They get placed in app/images/mission-patches.
• Suggest naming the mission patch teamname-reason-for-patch.png
• Each team can then replicate an existing section from the mission patch name, but swap out the content for their own.

Looks great! We should be able to edit down the intro and individual mission patch descriptions for Mavis’ patches, as some are quite long.

I also wonder if, once we get round to using the NHS.UK Eleventy Plugin, the hub layout (which uses cards) might work for this page (you can see an example of this layout here: https://x-govuk.github.io/nhsuk-eleventy-plugin/example/hub/). But I don’t think that separate piece of work should get it the way of rolling out this page.

Looks good. Have added some more. We can keep adding to it.
