[🐛 Bug]: unhandled exception in grid is reported as ScriptTimeoutException on the client

[joerg1985]

What happened?

We had a connection issue between the standalone server and the driver, this did raise a strange exception on the client side.

org.openqa.selenium.ScriptTimeoutException: Unable to execute request for an existing session: java.net.ConnectException: Connection refused: no further information: localhost/[0:0:0:0:0:0:0:1]:42081

How can we reproduce the issue?

`org.openqa.selenium.remote.ErrorCodec.createDefault().encode(new RuntimeException())` will return:
{
  "value": {
    "error": "script timeout",
    "message": "\u003cno message present in throwable>",
    "stacktrace": "java.lang.RuntimeException\r\n\tat ..."
  }
}

I think the cause of this error is the broken filter in `ErrorCodec.fromThrowable` here:
https://github.com/SeleniumHQ/selenium/blob/c9d0e356ea2f841ee2a3268f6b70052d6cac4fd8/java/src/org/openqa/selenium/remote/ErrorCodec.java#L158

This line should be: `.filter(err -> err.exception.isAssignableFrom(throwable.getClass()))`, am i correct?

I didn't wanted to silently create a commit to fix this, as others might have seen this wired `script timeout` exception in other client bindings.
