migrate website

[shaunagm]

We can't use PubPub past May 2025, unfortunately. ({More here](https://copim.pubpub.org/pub/copim-thoughts-pubpub-platform/release/2).)

It's unclear what we should migrate to. We could make a simple static site using Github pages, we could self-host pubpub (maybe doable on Github pages, for that matter) or switch to something like wordpress.

Things to consider:
-cost

• how easy it is to migrate
• how easy it is to edit/update on the new site itself

@KasiaHinkson just had a great idea which was to use the migration process as a pairing opportunity. Especially if we go the route of creating a static site hosted on github pages using, for example, jinja and python markdown to make something simple and custom, could be educational for folks interested in getting more web dev type experience (which is my @shaunagm's wheelhouse)
