Subject: [PATCH] Fix issue with stampit when using TS to check JavaScript
 (#27478)

* Fix issue with stampit when using TS to check JavaScript

**Caveat: This has not been tested within a TypeScript library.***  My knowledge of TypeScript is limited, so this has not been tested.  hence, I suggest @lummish and/or @koresar review this PR.

## What it's fixing

Currently I get the following error with the vanilla stampit example below, it applies to the `const Fighter = stampit(Character(...` line and TypeScript highlights the problem across the whole function:

```sh
Expected 0-1 arguments, but got 2
```

Example taken from main stampit example.
```JavaScript
import stampit from 'stampit';

const Character = stampit({
  props: {
    name: null,
    health: 100,
  },
  init({ name = this.name }) {
    this.name = name;
  },
});

const Fighter = stampit(Character, {
  props: {
    stamina: 100,
  },
  init({ stamina = this.stamina }) {
    this.stamina = stamina;
  },
  methods: {
    fight() {
      console.log(`${this.name} takes a mighty swing!`);
      this.stamina--;
    },
  },
});
```

* Make stampit() more generic

As discussed with @koresar.
