Per React docs, act is meant to be awaited and the callback passed to it to be async:

We recommend using act with await and an async function. Although the sync version works in many cases, it doesn’t work in all cases and due to the way React schedules updates internally, it’s difficult to predict when you can use the sync version.

We will deprecate and remove the sync version in the future.

We should probably create an ESLint rule for this in the future if there's no "official" one.
