Update action to use node24

[jimmymcpeter]

Node v20 is going to be EOL in April 2026 -- https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

The current 4.4.0 release runs using node20 -- https://github.com/googleapis/release-please-action/blob/v4.4.0/action.yml#L78

This is a feature request to provide a new major version using node24.

@chingor13 would you take a look at this please? Warnings are now being reported on workflows.

Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: googleapis/release-please-action@16a9c90856f42705d54a6fda1823352bdc62cf38. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/
