fix(ci): Properly check boolean input as string in publish condition (#448)

GitHub Actions converts boolean inputs to strings ('true'/'false').
Checking the value directly would be truthy even for 'false'.

Fixed by checking: publish_to_pypi != 'false'

This ensures:
- Runs when checkbox is checked (value: 'true')
- Runs with default value (default: true)
- Skips when checkbox is unchecked (value: 'false')
