Adds Zig version validation for publishing task

[muditchaudhary]

Description

This PR adds explicit Zig version (0.11) validation during the publishing process to ensure consistent artifact compatibility.

Changes:

• Adds version check during package publishing
• Does not enforce version check during normal build processes

Rationale:
Without version validation, artifacts could be published using different Zig versions, causing compatibility issues. By validating only during publishing, we ensure consistent releases while allowing developers to build from source using their preferred Zig version.

Testing

1. Running validateZigVersion task with incorrect Zig Version:

$> gradle validateZigVersion

> Task :validateZigVersion FAILED
Detected Zig version: 0.13.0
