[epic] Migrate "library" to Zotero (?)

@rufuspollock is already working on this.

Since Feb 23, 2022.

What we have is essentially a bibliography. The proposal here is to adopt the [Zotero reference manager](https://zotero.org) as our backend storage for the bibliographic items.

### Why do this change?

The main plus point of managing as README in git(hub) is:

* Making it easy to have moderated contribution via pull requests etc
* Quick publishing (it is just the github readme)
* Stars ⭐ (so some sense of interest / attention)

However, this is not necessarily optimal, especially as the bibliography grows. For example:

* Manual additions of new items including the key metadata
* No standard format for items (a change in standard format requires
* Painful to show the same item under multiple topics (manually copy and paste and if we correct anything needs correcting in multiple locations)
* Re-organizing of topics requires manual work
* No ability to sort by date or similar

Zotero + a renderer (static site) would seem to address a lot of this. At a minimum using zotero and very simple rendering should be able to reproduce what we have already and allow for easier addition of new material.

## Acceptance

* [x] We have made choice about using (trialling?) Zotero
* [x] We have a working Zotero library and have migrated some items there
* [x] We have instructions for others on how to contribute
* [ ] We have a PoC for how we get items back out and into a "README"

## Tasks

* [x] Set out the reasons for doing this **DONE. See Why below**
* [x] Migrate content to Zotero (trial)
* [x] Boot Zotero group library **DONE: https://www.zotero.org/groups/4600269/web3**
* [x] Migrate a test set of items (e.g. the general section) from the awesome repo to the awesome/general Zotero folder
* [x] create an awesome subcollection
* [x] create a general subcollection of awesome collection (or do we use tags??)
* [x] Migrate items following the migration process set out below in analysis (and update as needed)
* [x] Write up notes for others
* [ ] #52
* [ ] Script converting this back into markdown
* [ ] Research if any libraries / tools already exist in zotero ecosystem
* [ ] Use one or or decide to roll our own
* [ ] ...

### Misc

* [x] @EilidhRoss1 take @catherinet1 through Zotero and record notes from this briefing into section below about using Zotero so that we can write it up for others

## Analysis

### How to Contribute to the Zotero Library

* Install Zotero app
* Install Zotero extension
* Join the group library TODO

#### How to add Items / Migrate items

Aim: have "good" items where good means:

* Has snapshot or PDF etc (auto-generated usually if you add from the extension)
* Has proper metadata (full author name, date of piece, publication etc)

When migrating items:

* Notes in notes section (paste without formatting)
* [ ] Check if there is markdown support in Zotero notes field ...
