Docker PyPI script broken / outdated

[bitsgalore]

Running ./docker-package-pypi.sh fails at upload stage with:

Uploading distributions to https://upload.pypi.org/legacy/
Uploading jpylyzer-2.2.0-py2.py3-none-any.whl
100%|██████████| 65.9k/65.9k [00:01<00:00, 66.5kB/s]
Error during upload. Retry with the --verbose option for more details.
HTTPError: 403 Forbidden from https://upload.pypi.org/legacy/
Username/Password authentication is no longer supported. Migrate to API Tokens or Trusted Publishers instead. See https://pypi.org/help/#apitoken and https://pypi.org/help/#trusted-publishers

So script needs to be updated to API Token authentication.

Also happens when running ./package-pypi.sh directly.

After updating local .pypirc file (see here) + these changes PyPi packaging + upload works when running package-pypi.sh directly.

But apparently these changes break running the Docker file, which now results in:

Also note the CryptographyDeprecationWarning. Looks like the Docker build relies on an ancient (3.6) Python version.
