Update Readme | Getting started

At this point I am still failing with

 FAIL  src/services/jest-same-file-tests.ts
  ● Test suite failed to run

    Your test suite must contain at least one test.

      at onResult (node_modules/@jest/core/build/TestScheduler.js:175:18)
      at node_modules/@jest/core/build/TestScheduler.js:316:17
      at node_modules/emittery/index.js:260:13
          at Array.map (<anonymous>)
      at Emittery.emit (node_modules/emittery/index.js:258:23)

Either I did something wrong or there are further steps necessary.

(Here is a commit I created as-is when I got stuck. It contains both the jest-same-file-tests.ts and a cache-service.ts where I had initially hoped I could just "plug & play".)

The file I am trying to test:

import {tests} from "jest-same-file-tests";

class ToBeTested {
    doSomething(): string {
        return "something"
    }
}

tests("ToBeTested", () => {
    it("doSomething returns something", () => {
        const thingy = new ToBeTested()
        expect(thingy.doSomething()).toBeTruthy()
    })
})

(Import was auto-completed by IDE. Tried to instead explicitly call global.tests without change.)

The invocation I am trying to test it with:

npm test -- jest-same-file-tests

resolves #1

Those will by default filter by __test__ and thence never find a same-file test.

Added missing sup[p]ort here.
