Angular 16 runtime error Cannot set properties of undefined (setting 'black') at 91202 (tnp-core.mjs:471:34)

Hi!

I just migrated from angular 14 to angular 15 and then 16 while upgrading my packages but I get a runtime error when I include ng2-logger.

Uncaught TypeError: Cannot set properties of undefined (setting 'black') at 91202 (tnp-core.mjs:471:34)

I dug a little deeping and it seems to be caused by the "tnp-core lib/node-chalk-mock.ts" dependency declared for the ng2-logger project.

`-- [email protected]
  `-- [email protected]
    `-- [email protected]

I target es2022 in tsconfig.

This is caused by something for target es2022 that generates this wrong code in tnp-core/lib/node-chalk-mock :

const allObj = {
    black(a) {
        console.log(a);
    },
    gray(a) {
        console.log(a);
    },
    red(a) {
        console.log(a);
    },
    green(a) {
        console.log(a);
    },
    italic(a) {
        console.log(a);
    },
    magenta(a) {
        console.log(a);
    },
    bold(a) {
        console.log(a);
    },
    underline(a) {
        console.log(a);
    },
};
const map = new Map();
const all = Object.keys(allObj).map(key => {
    map.set(allObj[key], key);
    return allObj[key];
});
for (let i = 0; i < all.length; i++) {
    const e1 = all[i];
    for (let j = 0; j < all.length; j++) {
        const e2 = all[j];
        e1.prototype[map.get(e2)] = e2;
    }
}

If I override ng2-logger to use tnp-config/[email protected], then it works.

"overrides": {
    "ng2-logger": {
      "tnp-config": "16.0.14",
      "tnp-core": "16.0.14"
    }
  },

Let me know if I can provide any more information!
