🔨 handle OSError cases where traceback frames occur from built…

Hello. I'm not very familiar with open source contributions, so please bear with me if I'm a bit inexperienced.

Introduction

First of all, let me explain the background. I've been using the _render_traceback_ method of the traceback object, provided by the IPython.core.interactiveshell.InteractiveShell object that you created, in the showtraceback method. Thanks to this, I was able to create better error messages. I appreciate it. The following issue is related to the use of this method.

                    try:
                        # Exception classes can customise their traceback - we
                        # use this in IPython.parallel for exceptions occurring
                        # in the engines. This should return a list of strings.
                        if hasattr(value, "_render_traceback_"):
                            stb = value._render_traceback_()
                        else:
                            stb = self.InteractiveTB.structured_traceback(
                                etype, value, tb, tb_offset=tb_offset
                            )

Description

I noticed that in the recent 8.11 version, code was added to generate a traceback when the source code is too long. In this case, if the etb.tb_frame object is a built file or something similar, the inspect.getsourcelines(etb.tb_frame) method may raise an error. So I implemented a change to set the max_len to the minimum value and avoid the following condition when an OSError occurs. I think this approach can handle cases where errors occur while using the inspect.getsourcelines() method.

If there is anything I have done wrong or any procedures I should follow, please let me know. I would greatly appreciate it if you could leave a comment and I will make the necessary changes immediately. Thank you.
