Test Core against additional versions of Node.js (just Core build process)

[desrosj]

This adds additional test combinations to the workflow that tests the build process that run on Node.js versions 22 and 24.

22.x is the Active LTS version for Node.JS and scheduled to become Maintenance LTS in October when 24.x graduates to the Active LTS. Testing against these versions will help spot any potential compatibility issues that come up and can make upgrading in the future.

This pull request tests only the Core build process with these versions. This is an alternate approach to #9395.

This results in 12 additional jobs in the test matrix. These new jobs will only run within wordpress-develp, not within forks.

Trac ticket: Core-63170.
