Allow plugin to override builtin parsers when inferring parser (#17549 by @fisker)

Previously when inferring parser for file, builtin plugins are checked first, so plugins are not able to override parsers for files like .js.

// prettier-plugin-foo
export const languages = [
  {
    parsers: ["foo"],
    extensions: [".js"],
  },
];

// prettier.config.js
import * as prettierPluginFoo from "prettier-plugin-foo";

export default {
  plugins: [prettierPluginFoo],
};

prettier --file-info file.js

# Prettier stable
{ "ignored": false, "inferredParser": "babel" }

# Prettier main
{ "ignored": false, "inferredParser": "foo" }
