Vortex-python could benefit from a __version__ attribute for version references

[d33bs]

Issue Description

Thanks for the awesome work on this project! Python packages frequently provide an attribute __version__ for easy in-process references to the version of a package. I noticed that the Python package vortex-data is missing this reference.

For example, the following code should ideally render a version related to the package. Instead, it currently shows "unknown".

import vortex

getattr(vortex, '__version__', 'unknown')

Expected Behavior

See description.

Actual Behavior

See description.

Reproduction Steps

See description.

OS Version Information

Any

I acknowledge that:

• I have searched the Vortex repository (both open and closed Discussions and Issues) and confirm this is not a duplicate of an existing issue or discussion.
• I have checked the "Preview" tab on all text fields to ensure that everything looks right, and have wrapped all configuration and code in code blocks with a group of three backticks (```) on separate lines.
