Chore: Update Badges in README.md

[nelsonic]

Sadly the badges situation in the README.md
and correspondingly on NPM https://www.npmjs.com/package/aws-sdk-mock
are stale:

Todo

• Update GitHub CI build badge:

![GitHub Workflow Status](https://img.shields.io/github/actions/workflow/status/dwyl/aws-sdk-mock/ci.yml?label=build&style=flat-square&branch=main)

• Add hits badge:

[![HitCount](https://hits.dwyl.com/dwyl/aws-sdk-mock.svg?style=flat-square)](http://hits.dwyl.com/dwyl/aws-sdk-mock)

• Update dependency badge:

![Libraries.io dependency status for latest release](https://img.shields.io/librariesio/release/npm/aws-sdk-mock?style=flat-square)

• NPM Package version:

[![npm package version](https://img.shields.io/npm/v/aws-sdk-mock.svg?style=flat-square)](https://www.npmjs.com/package/aws-sdk-mock)

But just going to get it done fast so that the repo looks better.
(Just found out that NASA are using the package ... so tidying up to avoid bad impression)
