Fix admin/notes/tree-sitter/build-module/build.sh (bug#59789)

Besides the problem mentioned by Juri, which is fixed by removing

-cp tree-sitter-lang.in "tree-sitter-${lang}/src"
-cp emacs-module.h "tree-sitter-${lang}/src"

(we removed those files in an earlier commit, because they are not
used anymore.)

Now it also more parameterized and builds typescript and tsx
separately.

* admin/notes/tree-sitter/build-module/build.sh (topdir)
(repo, sourcedir, grammardir): New variables.
(Build): Make it parametric.
(Copy out): Use absolute path.

* admin/notes/tree-sitter/build-module/batch.sh (languages): Add tsx.
