Emacs itself doesn't actually include tree-sitter grammars. They decided to leave grammar installation up to the users, which does make sense as anyone can make a grammar and there's a few competing forks for some languages.

However have a look at treesit-auto, it has support for automatically installing grammars for a wide set of languages.
