Update CSE Machine to work with new version of @types/estree

[ZweZeya]

The current @types/estree needs to be updated in the js-slang. However, this requires an update in the frontend too, specifically the case machine in order for the new version of estree to be compatible with both the frontend and js-slang. This issue is closely linked to https://github.com/source-academy/js-slang/issues/1685
