Node.js 24 support

[rnsc]

This pull request updates the project to version 2.4.0, primarily upgrading the Node.js runtime from version 20 to 24 and updating documentation and usage examples to reflect the new version. It also adds instructions for rebuilding the distribution file.

Version and Runtime Updates:

• Bumped the project version from 2.3.0 to 2.4.0 in package.json and updated all usage examples in README.md to use @v2.4.0 instead of @v2.3.0. [1] [2] [3] [4] [5] [6] [7]
• Updated the Node.js engine requirement from ^20 to ^24 in both package.json and action.yml, ensuring the action runs on the latest supported Node.js version. [1] [2]

Documentation Improvements:

• Added a section to README.md with instructions on how to rebuild dist/index.js using ncc.

PR description created with CoPilot, but the code itself was updated by me.

Hi @Ana06, just chiming in as a user of this action — it would be great to get this merged. GitHub Actions now warns about Node.js 20 deprecation, and this PR would fix that for everyone.

@rnsc would you mind squashing your commits to clean up the history?

Thanks to both of you! 🙏
