connection.can_read() raises OSError when connection is broken

Version: 4.2.2

Platform: Windows 11
Description:
redis.asyncio.connection.Connection(), the class provides a can_read method, which is used, for example, in Client.parse_response.

However, unlike Connection.read_response() there is no error handling present to turn any OSErrors into asyncio.ConnectionError.
And so, the OSError bubbles up and causes problems, where we expect only asyncio.ConnectionError to occur.
This plays havoc with retry-mechanisms and automatic reconnect.

The issue is evident when the connection to the redis server is interrupted during a blocking call to pubsub.run() where a get_message call is made with a positive timeout.
