Remove unncessary use of tzdata in tests

[denini08]

This PR fixes the issue reported in #1260 where tests failed on Windows because the "Europe/Berlin" timezone could not be loaded.

On Linux, zoneinfo can read timezone data from the system, but on Windows it requires the PyPI tzdata package.

Pull Request Overview

This PR fixes a Windows-specific test failure by adding the tzdata package dependency. The issue occurred because zoneinfo requires timezone data that is available by default on Linux but must be installed separately on Windows.

• Adds tzdata package as a Windows-specific dependency for test environments
• Resolves timezone loading issues when running tests on Windows platforms

Hi @denini08, thanks for submitting a PR! 🙏

I'm not sure what to do about this, I will reply in the issue because there is nothing wrong with the PR itself, but I'm still unsure if we really want to solve this.

Hi, thanks for the follow-up!

Tests are failing. Please make sure to run nox locally and make sure all checks pass.

Also ideally squash both commits when things are working again.

@llucax thanks for the feedback, can you please check now?

[llucax]

Thanks, LGTM. Just a couple of nitpick comments, but for me this is basically ready to be merged if tests pass.

Thanks again for taking the time for this @denini08! I was sort of live-watching as you fixed all the many issue with GPG signing and DCO, I'm sorry the process is so complicated!

All seems to be looking good now! Will merge when ready.

I took the liberty of updating the PR title to more accurately reflect what it does.

It's a difficult process, but it was good that I learned some new things
