Local deployment issues

[ugurdogrusoz]

To ease the deployment of the tool locally, we can make the following improvements:

• Provide a docker file
• Specify the versions of the tools used for installing/deploying (e.g. npm and node)
• Provide exemplary curl commands

I added a Dockerfile to the root directory of the repository and wrote the instructions on how to use it in README. Dockerfile currently works only in Linux and Windows operating systems and does not work in macOS because of the Puppeteer related issues.

I also added recommended Node.js and npm versions that can be used during the deployment of the service as a note in README.

Finally, I detailed the existing curl and fetch API example in README with real data to make it more understandable.
