Dang, we forgot to update multiple files.

• https://openpmd-api.readthedocs.io/en/latest/maintenance/release_github.html
• Good example: Release: 0.15.0 #1391

Files:

• CHANGELOG.rst
• NEWS.rst
• docs/source/index.rst
• CITATION.cff
• docs/source/conf.py <-- problem for RTD builds
• setup.py <-- problem for PyPI releases

⚠️ The new_version.py is either still incomplete or was not run on this PR again. #1467

I did not find those files when setting up the script since I forgot searching for 0.16.0-dev and only modified those files that still had 0.15.0. For some reason, docs/source/index.rst has 0.15.1, so I did not find that either :/

[franzpoeschel]

I have pushed a fixed version of the new version script onto #1676

No worries, that happens :)
