chore(): Added CodeQL Analysis Workflow

[andoriyaprashant]

Description

This PR adds a GitHub Actions workflow to enable Codeql static analysis for Go code in the worker-operator repository.
The workflow will help identify potential vulnerabilities, maintain code quality, and run automatically:

• On push and pull requests to master
• On a weekly scheduled run (Sunday 00:00 UTC)
• Using GitHub’s official codeql-action with minimal required permissions

Fixes kubeslice/kubeslice#64

How Has This Been Tested?

• Verified workflow syntax with act and GitHub Actions syntax check.
• Confirmed that CodeQL initializes and analyzes Go projects in a test fork.
