Valentin Lorentz 63eb6672ea Revert generic 'The Limnoria Contributors' in copyright notices
This commit reverts db7ef3f025
(though it keeps the year updates)

After discussion with several people, it seems better to mention
copyright owners explicitly. eg. https://reuse.software/faq/#vcs-copyright
explains the issue of using VCSs to track copyright.

As db7ef3f025 only replaced mentions
of my name with 'The Limnoria Contributors', this commit only needs
to undo that + add one person who contributed to setup.py.
