Documentation: Web Modeling Editor GIF

[mengxihe]

What is the documentation issue?

The gif of Web Modeling Editor page is showing the association directions reversed.

Where is this documentation located?

https://besser.readthedocs.io/en/latest/web_editor.html

Suggested improvements

The association direction in the current GIF is reversed, which may cause confusion.
The options window for each class is labeled "Role", but it should describe the other class instead.
