Add API option for editing Lists

[C0rn3j]

Would be nice if Lists could also be edited via the API, just like Cards can be, I wanted to edit list color in the API - this does not look possible at the moment - https://wekan.github.io/api/v7.44/#get_list

Anyone that needs more APIs, can send PR for additional API. Most APIs has been added by various WeKan contributors.

https://github.com/wekan/wekan/blob/main/models/lists.js#L568

https://github.com/wekan/wekan/blob/main/models/cards.js#L3504

Also add example of using API to api.py:
