Bug: tzdata hard dependency

[gnzsnz]

This dependency is blocking updates on tzdata tzdata = "^2025.2"

The fix is quite simple, tzdata = "*" or tzdata = ">=2025.2" in case it's needed.

Analysis, this was reported on #188 and fixed on 2e9bcdf . However the fix has a "caret requirement" -> tzdata = "^2025.2". tzdata does not follow "semver", it follows some version of "calver" YYYY.Minor. I believe tzdata = "*" is the "best" option.

yeah, default package manager mistake there. fixed in next for a soon release again.

new unification of this, eventkit, and the nest_asyncio all have next branches hopefully going out in a new update soon.
