Media carousel from feature request #876

[zarSou9]

This adds the ability to create media carousels in articles using this format from google docs. This (I'm pretty sure, but @nemo can you verify) translates in markdown to something like the following:

::: carousel
- [Cat Image Title](https://media.4-paws.org/d/2/5/f/d25ff020556e4b5eae747c55576f3b50886c0b90/cut%20cat%20serhio%2002-1813x1811-720x719.jpg)

- [Cat Gif Title](https://i.giphy.com/SKDiTL793TGiaiV9Kv.webp)

- [Cat Video Title](https://www.youtube.com/watch?v=cytJLvf-eVs)

:::

Which is then parsed, and replaced with a media carousel component which looks like this:

carousel.mov

There are a lot of extra spaces added, but markdown output looks ok on

View on site works mostly as expected. I suggest making the left-right arrows a bit thicker.

Interface on mobile is not ideal, but I think it's fine. We can improve it if we end up using it extensively.

@Algon-33 do you have the tools to test it in a dev branch?

I don't know how hard that is, but it would be nice to be able to have captions that appear under the images to clarify what they are.

Agreed, I've just added it

Looks good to me!
