CPT-1 Use Ubuntu 22.04 LTS in Dockerfile

[borna-ng]

Changes

• ttf-dejavu package has been renamed to fonts-dejavu
• tzdata package is not installed by default so it is installed manually
• wkhtmltopdf
  • Currently used Debian package (0.12.5) cannot be installed because it depends on old libssl
  • We use the latest version packaged by original authors (0.12.6) which is at the same time the latest version available since the project is not maintained any more
  • We didn't install the same version packaged by Ubuntu because that one is not using patched Qt which provides CLI flags that we depend on
• Python
  • Ubuntu 22.04 LTS comes with Python 3.10
  • Current odoo dependencies do not compile from Python 3.10 onward either because of Cython version changes or Python C API changes
  • We use pyenv to keep the current Python version which is 3.8
    • Some additional development system libraries are installed because Python is built from source
    • This also complies with new policy of Debian-based distributions to avoid installing system-wide Python dependencies in order to avoid breaking system packages (alternative is to use pip --break-system-packages)
  • APT's python3-magic was replaced with pip's python-magic
  • APT's python3-cairocffi was replaced with pip's cairocffi
• Decreased Docker image size from 2.03 to 1.83 GB

Future notes

• Explicitly delete ubuntu user
  • The new Ubuntu 24.04 LTS image comes with ubuntu user (uid=1000)
  • We should remove the ubuntu user since it is not needed and causes trouble with permissions when mounting sources into a dev container
  • That way odoo user gets to have uid=1000
• wkhtmltopdf will have to be compiled from source (good luck 🍀)

Looks good. The wkhtmltopdf should be tested later because in the past we had sometimes problems with wrong layouts etc. But probably not a big deal with the minor update.

@christophlsa

We have some tests failing in the corresponding PR in odoo-addons-jobrad so we are currently looking into it.

All automated tests are passing: https://github.com/jobrad-gmbh/odoo-addons-jobrad/pull/3070

Manual testing in the sandbox still required: https://erp.cpt-1.dev.jobrad.org

Looks good to me. I just had a minor comment.
