🩹(backend) get current release from pyproject.toml

In Sentry it is nice to have the release version,
it will help us to track the errors.
get_release was returning NA, we fixed it by
getting the version from pyproject.toml.
To do so we use tomllib, native library since
Python 3.11.
Our docker image is using Python 3.12.6, but our
CI was using Python 3.10, so we bump the CI python
version as well to be able to use tomllib.
