docs(FAQ): update dependency installation troubleshooting

Update the FAQ to clarify the dependency installation issue when using magic-pdf. Ensure
users are directed to install the specific version of magic-pdf that resolves the dependency

and provides a direct solution for users encountering the "Required dependency not installed"
error.
