[Bug]: Traceback Error with --skip-text option

[FelixKrickl]

Describe the bug

On Windows 10, ocrmypdf (version 16.6.0, installed like in the readthedocs.io manual) has issues in regards of the JBIG2 utility from texlive. Since I don't know if ocrmypdf is even supposed to use this it might also be an error due to PATH-variable settings. Despite getting the output that I needed, there was also an Traceback Error from Python3.12, see the codeblock.

Steps to reproduce

1. Download pdf from https://epub.uni-regensburg.de/10399/1/Dissertation_Zhao.pdf into your current working directory.
2. run the ocr command:
`ocrmypdf.exe --skip-text Dissertation_Zhao.pdf out.pdf`

Yes, I seem to recall this came up many years ago. texlive's jbig2 isn't compatible.

I'm most of the way to create a Python/Rust library that handles jbig2 to avoid shelling out to that subprocess, which is a problem for many... just need to get there. As such I won't bother making the checks more robust.
