core: bump nsfw to ^2.1.2

Improvements have been made to the library. Notably a bug was fixed
where some folders were not picked up by the watchers if created too
quickly and an issue on Windows was fixed where watching didn't work at
all.

This commit updates our code to use the new typings distributed by
`nsfw` itself and re-enables file watching testing on Windows.
