Upgrade GitHub Actions for Node 24 compatibility

[salmanmkc]

Warning

You may currently be seeing a warning like this in your workflow runs:

Node.js 20 actions are deprecated. The following actions are running on Node.js 20
and may not work as expected: actions/github-script@60a0d83039c74a4aee543508d2ffcb1c3799cdea, actions/checkout@08c6903cd8c0fde910a37f88322edcfb5dd907a8.
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/

The exact actions listed will vary per workflow.

Upgrades GitHub Actions to versions that support Node 24, since Node 20 is reaching EOL in April 2026.
