Envelope_sender of V12.0 not included

[Creyox]

What version of Gophish are you using?: 12.0

Brief description of the issue: The documentation is not updated and does not include the added envelope_sender in V.12.0. Additionally, the envelope_sender can not be requested via the Python wrapper, it is not included in the template processed by the Python wrapper.

What are you expecting to see happen? : The Python wrapper shall return the envelope_sender when requesting a specific campaign / the template of it.

What do you see: A direct API call is possible and returns the envelope_sender, but the Python wrapper is not updated.
