API-Docs: "Email" need to be deleted from post-json if no mail is given

[wellemut]

Problem

It is unlogical, that the backend does not except an undefined or empty "email": null filed.

Instead you have to remove the whold "email" attribute from the json

• Describe this specification in the swagger Documentation!

(See the error-finding: kartevonmorgen/kartevonmorgen.ts#43)

Remove unnessesary restrictions

POST Events has some restrictions, which makes it quite complicated: https://app.swaggerhub.com/apis/Kartevonmorgen/openfairdb/0.10.5#/Events/post_events
Why do you need allways to give an "Creators-Mailadress" even if it is an anonymous entry?

Solution: Post events without mailadress

• Please remove the need to give a mailadress (equal to the way it works with places)

This Part seems to be old:

Creating new events is only allowed for registered organizations by authorizing themselves with an API token. These organizations must own reserved tags.

• Please remove it from the API-Description
