pip problem with Debian 12 installation of python3-deprecation

[ultradian]

Description

I think there is some problem in the interface between pip and Debian when installing python3-deprecation via apt. Afterwards I do a pip3 list and see thinks it has version:
deprecation 2.0.7
although apt tells me:
python3-deprecation is already the newest version (2.1.0-2)

Expected behavior

should get
deprecation 2.1.0-2
instead since that is what is installed in the system

pip version

pip 23.0.1

Python version

Python 3.11.2

OS

Debian GNU/Linux 12 (bookworm)

How to Reproduce

apt install python3-deprecation
pip3 list

Output

deprecation 2.0.7

Try running pip3 show deprecation and dpkg -L python3-deprecation to confirm you're looking at the same package (on the same path). If the paths match this is very likely this is a metadata issue on debian's side, pip just reports the metadata from the Python package.

You should be able to find this from the pip3 show command by looking inside the path for a directory called deprecation-{version-number}.dist-info and inside that should be a file called METADATA which near the start should be a line Version: {version-number} which matches the version number of the directory and what pip reports.
