improve docstrings in Autoupload enum

[denniswittich]

Rephrases the docstrings in the Autoupload enum to better reflect its role as a configuration type rather than an active component.

Changes:

• Rewrites class docstring to describe the enum's purpose as configuration options
• Changes member docstrings from action statements to descriptive mode definitions
• Removes misleading implications about the enum performing actions itself

The enum is a pure type definition, and these changes make its purpose clearer to developers.

@NiklasNeugebauer Did you check if this variant still works e.g. on ubuntu 22?

tests are running fine without libgl.
The Docker image works with the new packages, though I also doubt it really needs the libraries.
If anyone has other specific needs, like for OpenCV visualization, they should have this expressed in their system configuration or Dockerfile.
