Chore: Fix Playground loading issue, simplify release workflow, fix ESLint test parsing, and Improve test docs

[danish17]

This PR improves the project's release reliability, streamlines CI/CD, and resolves development environment issues.

Key Changes

• WordPress Playground: Fixed an issue where WordPress Playground was unable to load the plugin reliably from the statically.io CDN. The plugin source has been switched to use GitHub Releases for better stability.
• Release Workflow: Simplified the GitHub Actions release process by removing the automated deployment to the dist branch. The workflow now focuses on creating GitHub releases and uploading the built plugin ZIP.
• ESLint Configuration: Resolved parsing errors in tests/js/setup.ts and other test files by including tests/js/tsconfig.json in the ESLint parserOptions.project configuration.
• Test Documentation: Refined JSDoc comments in view.test.ts to include explicit parameter and return types for helper functions, improving developer experience and code clarity.

Verification

• Plugin now loads reliably in WordPress Playground via GitHub Release URL.
• ESLint parsing errors in the test suite are resolved.
• GitHub Actions workflow is updated and valid.
• Unit tests pass successfully.

Update: I tested this blueprint from this branch, and it worked 100% of the time with very fast load times. https://github.com/rtCamp/carousel-kit/blob/fix/playground/blueprint.json
