sentry-ruby now sends events asynchronously by default with its background worker (supported since 4.1.0).
The `config.async` callback has become redundant while continuing to cause issues.
(The problems of `async` are detailed in https://github.com/getsentry/sentry-ruby/issues/1522)
Therefore, we encourage you to remove it and let the background worker take care of async job sending.
It's deprecation is planned in the next major release (6.0), which is scheduled around the 3rd quarter of 2022.
