CI: Update actions/github-script to a version that uses Node.js 20+

[kaylareopelle]

The version of actions/github-script we use in multiple workflows runs on Node 16. This adds a deprecation warning annotation to our runs, for example:

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/github-script@. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

Update the version of actions/github-script used in all our workflows to a version that uses Node.js 20 or higher. At the time of creating this ticket, Node.js 22 was the most recent version.
