[DEFECT] Windows batch file does not generate full user manual

Defect Description

Describe the defect

What did you expect to see happen?

On Windows running the .bat file should generate the full user manual.

What did you see instead?

raven_libraries conda environment is not activated during execution, so if packages needed to generate the documentation are not in the user's base environment, the full user manual is not generated.

Do you have a suggested fix for the development team?

Activate the raven_libraries conda environment before running the script/generate_user_manual.py script.

Describe how to Reproduce Steps to reproduce the behavior:

Be on Windows
Run make_docs.bat
