* Add missing dependencies on `@types` packages
Because we import the typescript source from matrix-js-sdk rather than the
`.d.ts` files, `tsc` ends up type-checking the js-sdk source. That means that
we need to have the `@types` packages that js-sdk needs.
* Add missing type definitions for `setInterval` and `setTimeout`
Our source assumes that `setTimeout` returns a number, not a
`Timeout`. If we `yarn link` js-sdk, then (somehow) we end up using the
definitions from there, but it's not really correct.
* Configure knip to ignore new deps
