Move read_text to executor (#5688)

* Move read_text to executor

* Fix issues found by coderabbit

* formated to formatted

* switch to async_capture_exception

* Find and replace got one too many

* Update patch mock to async_capture_exception

* Drop Sentry capture from format_message

The error handling got introduced in #2052, however, #2100 essentially
makes sure there will never be a byte object passed to this function.
And even if, the Sentry aiohttp plug-in will properly catch such an
exception.
