bumping whenever dependency

[mhdask]

Why

Started working on packaging infrahub for nix/NixOS - For that, some dependency bumping is needed, to align with the other versions of dependencies in nixpkgs
This bumps whenever to 0.10.0

What changed

• Bumped whenever to 0.10.0
• Due to API change, had to adjust usage of rounding for ZonedDateTime
• 0.10.0deprecates py_datetime in favour of to_stdlib

How to review

• Needs to be tested against infrahub-testcontainers from release-1.10 due to dependencies against prefect-client

Checklist

• Tests added/updated
• Changelog entry added (uv run towncrier create ...)
• External docs updated (if user-facing or ops-facing change)
• Internal .md docs updated (internal knowledge and AI code tools knowledge)
