/opt/X11/lib/pkgconfig freetype2.pc fontconfig.pc

### Describe the bug
It was impossible for me to install Manim. Using Apple MacBook Air M3. Following every step (brew and pip3 installations) always got me to the same absurd error with fontconfig version. Mine was quite more higher but the installer said it was lower than needed

**Code**:
I run

cd /opt/X11/lib/pkgconfig
mv freetype2.pc -freetype2.pc
mv fontconfig.pc -fontconfig.pc

pip3 install manim

and it worked!
