Docs for presence

[katfang]

1. Docs for Presence
   • Pushed to the "top" the react library for presence, however standard service usage is below.
2. Edits the React presence library so it doesn't rely on tailwind
3. Added test on the TS side for connecting a subscriber (largely to confirm docs code). Unfortunately, it's not directly liftable into the docs, but did my best to leave bread crumbs as to what's happening.

Bug: missing comma after libraries: [presenceLibrary()]. Since ASI doesn't apply inside an object literal, copy-pasting this snippet produces a SyntaxError at initialize. The Python tab just above uses libraries=[presence_library()], and the two later TypeScript snippets in this file both have the comma, so this looks like a typo.

Suggested change

	libraries: [presenceLibrary()]
	libraries: [presenceLibrary()],

Bug: the prop is named id, not presenceId. Under a heading that lists the component's props (and next to subscriberId, which is a real prop name), a reader will write <Presence presenceId={...}> and fail type-checking.

The component declares its props as:

reboot/reboot/std/react/presence/index.tsx

Lines 22 to 28 in 5e4b9b4

	export const Presence: FC<{
	id: string;
	subscriberId: string;
	children: ReactNode;
	}> = ({ id, subscriberId, children }) => {
	const presence = usePresence({ id });

The example further down in this doc correctly passes the local variable presenceId to the id prop.

Suggested change

	* `presenceId` is the `string` ID of the `Presence` instance you want to track
	the subscriber for.
	* `id` is the `string` ID of the `Presence` instance you want to track
	the subscriber for.
