chore: pin @types/node to fix CI check failures

[abarker-launchdarkly]

This PR pins @types/node at 24.1.0 in order to fix CI check failures

24.3.0 is causing errors such as:

../../../node_modules/@types/node/child_process.d.ts(309,9): error TS1165: A computed property name in an ambient context must refer to an expression whose type is a literal type or a 'unique symbol' type.
