Bug report

Why remove the id of runtime chunk from the entriesPart in JsonpTemplatePlugin

What is the current behavior?

• ./dist/runtime.js

// ...

/******/ 		var installedChunks = {
/******/ 			666: 0
/******/ 		};

// ...

• ./dist/main.js

(window["webpackJsonpw5"] = window["webpackJsonpw5"] || []).push([[179],{

/***/ 138:
/***/ (() => {


console.log(1);


/***/ })

},[[138]]]);

If the current behavior is a bug, please provide the steps to reproduce.

• ./src/index.js

console.log(1);

• ./webpack.config.js

module.exports = {
    entry: {
        main: './src/index.js'
    },
    optimization: {
        minimize: false,
        runtimeChunk: 'single'
    }
};

• ./package.json

{
  "devDependencies": {
        "webpack": "5.0.0-beta.23",
        "webpack-cli": "^4.0.0-beta.2"
    },
    "scripts": {
        "build": "webpack --config webpack.config.js",
    }
}

What is the expected behavior?

• ./dist/runtime.js

// ...

/******/ 		var installedChunks = {
/******/ 			666: 0
/******/ 		};

// ...

• ./dist/main.js

(window["webpackJsonpw5"] = window["webpackJsonpw5"] || []).push([[179],{

/***/ 138:
/***/ (() => {


console.log(1);


/***/ })

},[[138, 666]]]);

When I use webpack@5.0.0-beta.18 and below versions, the behavior is expected.

Other relevant information:
webpack version:
Node.js version: v13.14.0
Operating System: macOS Catalina 10.15.2

That was not intended, it's a bug. Do you want to send a PR?
