GitHub uses tree-sitter grammars for syntax highlighting the following languages: CSS, Go, JavaScript, EJS, ERB, HTML, Python, Ruby, TypeScript and CodeQL. The JavaScript tree-sitter grammar is here: https://github.com/tree-sitter/tree-sitter-javascript (grammar.js and src/scanner.c are the important files)

As this help page of GitHub.com says, they’re using the Linguist library, which is written in Ruby.

Linguist’s highlighters for each language are within vendor/grammars. And a list of supported languages can be found here, here, and here.
