Add Node.js 24 to test strategy (WordPress#71091)

* Dynamically set `node-version-file` input

When both `node-version-file` and `node-version` are passed to `actions/setup-node`, a warning is output.

When inputs are empty, they are ignored. This will silence the error while keepign the same functionality.

* Add Node.js 24 to test matrices.

* Revert "Dynamically set `node-version-file` input"

This reverts commit 8f95ec0.
