   Can you detail why these changes are necessary? Looks to me like these actions are working fine. Are any EoL?

   These changes are not “necessary” in the sense that the existing action version are EoL. But these changes will become necessary in the future as actions migrate the Node runtime they are running on. All the actions updated here use Node 24.0 so it’s only a matter of time before the older actions use a Node version that is not automatically available on the machine you are using.
