Remove FORCE_JAVASCRIPT_ACTIONS_TO_NODE24 variable

Removed FORCE_JAVASCRIPT_ACTIONS_TO_NODE24 environment variable. The 3P actions plugins in use here all depend on Node 20, so this is not needed. In general the internal runner node can use a different version of Node (even though Node 20 is slated for deprecation in September of 2026).
