ci: skip caching of node_modules (#200)

I have no idea why I originally did it this way but it makes no sense.

- restore node_modules from cache (if any)
- run `npm ci`
  - delete node_modules
  - recreate node_modules from scratch
- save node_modules into cache

The caching is completely pointless as it's restored just to be deleted right away. It just wastes about a minute of time per workflow.
