Exception with latest version

[priv-kweihmann]

Environment

• Pydoc-Markdown Version: 4.6.4
• Python Version: v3.7.15, v3.8.14 (pipelines for 3.9-3.11 haven't run yet but I suspect them to fail with the same as well)
• Operating System: ubuntu 20.04 (github actions ubuntu-latest image)

Describe the bug

only difference between the latest good run and the failing is

exceptiongroup-1.0.1 > exceptiongroup-1.0.2
pydoc-markdown-4.6.3 > pydoc-markdown-4.6.4

Expected behavior

No exception, as the point release before worked fine

[priv-kweihmann]

Interestingly it works with 3.11.0 and 3.9.15
