libsynctex should be a mandatory dependency of zathura

Hi.
The libsynctex dependency is optional in Artix (https://packages.artixlinux.org/details/zathura) while it is mandatory in Arch (https://archlinux.org/packages/community/x86_64/zathura/).
When I installed zathura, I could not run it without installing libsynctex, because it would give the following error:

zathura: error while loading shared libraries: libsynctex.so.2: cannot open shared object file: No such file or directory

Thanks to move libsynctex as a mandatory dependency.

Update to fix, will be built and available once mirrors sync.
