Migrate from bundlesize to size-limit

- Remove bundlesize dependency
- Add @size-limit/preset-small-lib and size-limit dependencies
- Convert bundlesize config to size-limit format
- Add Bundle Size Check job to CI workflow
- Update GitHub Actions to v4 (checkout, setup-node)

Bundle size limits:
- dist/react-final-form-html5-validation.umd.min.js: 2 kB
- dist/react-final-form-html5-validation.es.js: 3 kB
- dist/react-final-form-html5-validation.cjs.js: 3 kB
