Remove dist/bundle.js from the repo

[derberg]

Reason/Context

dist/bundle.js was always there in the repo, but then we added release automation and it anyway is always available, fresh and nice on the release level, example: https://github.com/asyncapi/parser-js/releases/tag/v1.14.1

In other words: bundle.js is already available on a release level + npm package.

Having it in the repo only causes confusion and continuous issues:

• with every single contribution as people commit it, then they have to remove it and it is causing headaches
• with long-living release branches that take months to release and in meantime bundle.js on master gets updated

What do you think?

Description

We need to:

• remove bundle.js from this repo
• update readme information that bundle.js is also available on a release level
• add bundle.js to .gitignore
• update package.json to make sure bundle.js is an exception and that even though it is ignored, it should be pushed to npm

Let's remove it.
