chore: improve release automation

[andredestro]

This PR streamlines the release process by consolidating multiple manual steps into a single GitHub Action. Previously, releasing involved updating the changelog manually, merging a separate PR, and running two separate workflows.

Changes

• Consolidated release steps (changelog update, CocoaPods release, GitHub release) into a single workflow.
• Integrated semantic-release to automate versioning and changelog generation, similar to Capacitor plugins.
• Updated CI/CD scripts and workflows for consistent and automated releases.

Outcome

• Releasing the library now requires just one GitHub Action trigger.
• Reduces manual steps, improves reliability, and speeds up the overall release process.

Just a reminder to set the GH token secret after merging the PR (or right now if you'd like), otherwise we might forget.
