Update from Node20 to Node24

[samyouel]

As announced by Github last year:

Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: Asana/create-app-attachment-github-action@latest. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Node.js 20 will be removed from the runner on September 16th, 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/

➡️ Please could you upgrade the action to run in node24, otherwise from June 2nd onwards we would not be able to use the action anymore which would be sad.

Thanks so much!

GitHub gave another couple of days until the 16 June! Yay!
Thanks so much for considering upgrading this workflow :)
