build: remove main function from `.jison` files
When converting a `.jison` file into a CommonJS module, jison by default adds a main() function that calls `require("fs");` Even though the main function is never used in the browser, because `fs` is a Node.JS only module, this causes some esbuild issues. To disable this, we can just set an empty main to the jison generator.
