fix: add unicode tree-sitter include directory

[f46b83ee9]

This Commit is used to avoid some errors in the build process using Ubuntu that I stumbled upon :

Discussed in Discord (https://discord.com/channels/756287461377703987/1110990884876603523)

When I tried in a proper docker container using Ubuntu image 20.04, I hit this error :

/build/source/third-party/tree-sitter/tree-sitter/lib/src/././unicode/utf8.h:37:10: fatal error: unicode/umachine.h: No such file or directory
   37 | #include "unicode/umachine.h"

This error can be resolved using by fixing include directories for the tree-sitter library, either by editing the includes, or by adding an include path.

I decided using the CMake fix since it doesn't modify the vendor sources.
