[v2] docs(menu): fix some syntax issues (#4726)

* [v2] docs(menu): fix some syntax issues

- one line wasn't properly indented
- one line was missing a closing brace and wouldn't compile as such

noticed this while [answering a question on SO](https://stackoverflow.com/a/79827672/3431180) which linked to this page

* add changelog entry per PR template

* consistent 4 space indentation
