[BUG] Development guide missing instructions for installing opencc on Apple Silicon

[laike9m]

Describe the bug
Following the development guide, running python manage.py check gives OSError: dlopen(libopencc.so.1, 0x0006): tried: 'libopencc.so.1' (no such file)...

Desktop (please complete the following information):
Mac M1

Additional context
It appears that opencc needs to be built from source on Apple Silicon
BYVoid/OpenCC#701
while for other architechtures it has pre-built wheels

An alternative solution might be to use opencc-python-reimplemented, though there's no guarantee if it works as good as the official version

[laike9m]

Verified that the following steps can work:

1. Make sure opencc has not been installed by pip, i.e. pip uninstall opencc

2. Manually build and install opencc, make sure it's using the right Python version/environment

   git clone [email protected]:BYVoid/OpenCC.git
   cd OpenCC
   make python-build
   make python-install
   

3. Verify if it's installed correctly, notice the output of Location

pip show opencc

Thanks for reporting and investigation!

There were some other issues on macOS like #5 , not sure that's fixed on Apple's end or not.

Please feel free to submit PR for install docs

Sure, I'll create a PR

OpenCC is no longer used in latest code
