feat: migrate to ESM and update dependencies (#949)

* feat: migrate to ESM and update dependencies

- Migrated the project to ESM to support the latest `@actions/*` package versions.
- Updated dependencies to their latest versions, including `@actions/core`, `@actions/github`, and others.
- Replaced `.prettierrc.js` with `.prettierrc.json` for configuration.
- Updated ESLint configuration to use ESM and added new rules.
- Refactored test files to use `jest` with ESM imports.
- Removed deprecated files and updated import paths to use `.js` extensions.
- Added new files for improved configuration and removed unnecessary mocks.
- Updated README to reflect breaking changes in version 7.

* docs: update README to clarify ESM migration details and adjust TypeScript configuration
