The error shows a dependency conflict between docutils and m2r2:

Let's modify your docs/requirements.txt to specify compatible versions:
requirements.txt
The key changes are:
Changed docutils requirement from <0.18 to >=0.19 to match m2r2's requirements
Specified m2r2 version >=0.3.3 to ensure we get a version compatible with newer docutils
This should resolve the dependency conflict while maintaining compatibility with mermaid diagrams.
