feat(publish): add publishing options

[Gijsdeman]

Splits the publishing config in different files.

To test before merging:

• Versioning publish workflow
• NPM publish workflow
• Docker publish workflow

To add before mering:

• Update the README
• Adding some examples
• Consider adding a yarn install --development or npm ci to the NPM publish

For the last step; I intentionally did not do this as this once again would have led to a difference between yarn and npm. However, I feel like this should be a step part of the "built-and-lint" flow instead, where you write a test that checks if all your packages can be installed without issues. How this would look like under the hood I am unsure, but that is a problem for later.

Closes #4.
