Update docs

[alina-beck]

🍰 Pull request

• fixes a few typos
• replaces internal references with absolute links to make them work on GitBook
• updates the "Edit this Documentation" part to work without the "Edit on GitHub" button
• adds information on how to allow Apoc procedures on the Neo4j server
• removes the line "This directory is not required, you can delete it if you don't want to use it." from all webapp docs (I assume they originate from the Nuxt.js templates but since we are using these directories and they can obviously not be removed I thought deleting the line might be less confusing for new contributors. Unless you have a good reason to keep it there?)

Issues

• None

Todo

• Maybe update the Contribution docs to include the current mentors and developers?

I absolutely ❤️ it! Thank you so much! I have nothing to request except for one thing, see my suggestions below.

@alina-beck you have a new follower on Github. I will also add you to the team "Volunteers", so that will give you write permissions into our repositories. Write permissions means, you can push branches and you can also merge into master (after approving code review).

In this case it would be better to keep the relative path. Why? If you send in a PR and let's say you changed the referenced file and if a code reviewer would click on the link, she would be redirected to the master branch. You can try it out yourself by clicking on "Preview" and then click on the link.

You're right, that's not ideal. The reason I changed it is that the relative paths are not working on GitBook. For some reason they add a /README.md to the end of the link and since there are no READMEs in the cypress/integrations folder you land on a 404 page...

Any idea how to get this working for both use cases?

[roschaefer]

No! In that case I'll approve this and merge. 👍
