ci: Move Github Release Action to Final Step

[nickolas-dimitrakas]

Background

The release workflow previously created the GitHub release before pushing to CocoaPods Trunk. This meant that if the Trunk push failed, the GitHub release would already be created, making it harder to retry the release process.

What Has Changed

• Swapped the order of "Push to Trunk" and "Create Github release" steps in the release-from-main.yml workflow
• CocoaPods Trunk push now happens first, followed by GitHub release creation
• This ensures that if the Trunk push fails, the GitHub release won't be created yet, simplifying retry logic

Checklist
