This is Emacs; how can you assume such hard-coded paths are even possible?

Of course, they aren't hard-coded!  Emacs looks in the standard directories
for shared libraries, then in user-emacs-directory, then in the directories
mentioned in treesit-extra-load-path.

Adding this to treesit-extra-load-path is fine.  Alternatively, install the
shared library where you have the other shared libraries on your system
(a.k.a. "standard places").
