[DOC] Add all documentation snippets to the cookbook.

[smehringer]

We often talked about that the cookbook is mainly for searching via Strg + F.

This adds all snippets from our documentation to the cookbook (via an automated script). This way, if the user remembers they have seen something in some snippet, but doesn't remember where, it can be found in the cookbook.
