[Bug] ZoneInfo module has a dependency on tzdata module in Windows

[nxchoople]

Describe the bug
ZoneInfo uses the time zone data natively in Linux when selecting a time zone. When you use Windows, that capability isn't there and requires the tzdata module to function. If you don't install the module on Windows, then you will receive an error that ZoneInfo can't find the time zone key.

Branch/Container
master

To Reproduce
Create a job with the time zone defined on a Windows OS using Calm DSL.

Expected behavior
The job should be created without any errors when specifying the time zone.

Findings/Troubleshooting Done
ZoneInfo needs the tzdata module on Windows.

Screenshots

** System Configuration:**

• OS: Windows Server 2019
• Python: 3.11

We should include the tzdata module in the requirements.txt file so that it is available when running Calm DSL natively on Windows.
