Should we hide some IDs from the screenshots?

Should we hide some IDs from the screenshots?

I don't think they are leaking anything so I wouldn't bother

LGTM

We should also update the initial part of this page:

1. The page description should mention Arweave given that it's one of the examples.
2. The first paragraph should mention that users can use either centralised storage or decentralised storage. At the moment it reads as if an HTTP URL is the only option.
3. The first screenshot should be updated as it's currently out of date.

Also, some formatting changes:

1. Overview should be an H2 title
2. Rather than having Hosting Services as an H3 title, I would have two separate H2 titles: Decentralised Hosting and Centralised Hosting
3. Arweave, AWS and Azure should be H3 titles instead of H4 titles.

The ideal behind these formatting changes is to get a the side menu to work better and nicely show the different sections of this page, which should help with navigation.

Great suggestions @jamiehewitt15 👍 I've integrated them all and updated the PR.
Please let me know if you see something off or if you have other things you think should be changed.
Thanks 🙏
