1.5.1 Autogenerated release tars still say "dev" instead of release

While updating the Fedora package, I noticed that the automatically generated release tar here on GitHub still says "dev" in the info.json file:

https://github.com/G-Node/nixpy/archive/refs/tags/1.5.1.tar.gz

because the info.json file at that tag/commit still says so:

https://github.com/G-Node/nixpy/blob/b140b789ee301348d8a07562775860490188f377/nixio/info.json#L2

However, if one uses the released tar (manually generated?), it says "release":

https://github.com/G-Node/nixpy/releases/download/1.5.1/nixio-1.5.1.tar.gz

So they're not quite in sync here, and if one uses a git clone, for example, one would get the version as 1.5.1.dev0 and so on. So, could the info.json file also be updated in the repo when a new release is tagged please so that the release and tagged tar are identical?
