You need to use the symbol 'gomod' and not 'go-mod' in
treesit-language-source-alist.

Here is your fixed init.el:

#+begin_src emacs-lisp
(setq treesit-language-source-alist
          '((go . ("https://github.com/tree-sitter/tree-sitter-go.git";))
                (gomod . 
("https://github.com/camdencheek/tree-sitter-gomod.git";))))
(add-to-list 'auto-mode-alist
                         `("\\.go\\'" . go-ts-mode))
(add-to-list 'auto-mode-alist
                         `("\\go.mod\\'" . go-mod-ts-mode))
#+end_src
