build: add patch for js-waku not found

When running the test with `jest`, it errored with
```
Cannot find module 'js-waku' from 'node_modules/@xmtp/xmtp-js/dist/cjs/src/utils.js'
```

The problem seems to be this issue
waku-org/js-waku#770.

Until this is resolved, we use a local patch as this only occurs when running tests.
