* lisp/treesit.el (treesit-install-language-grammar): fix recipe
addition to `treesit-language-source-alist`

Bug: `treesit-install-language-grammar` adds repeated language
entry to `treesit-language-source-alist` causing circular list.

Recipe to reproduce:
1. `M-x treesit-install-language-grammar` `bash` (enter all defaults)
2. `M-x treesit-install-language-grammar` `bash`
