Update paths to type declaration files in package.json

[Miodec]

I was battling my monorepo setup and almost got everything to work except importing slim-select. I was getting an error:

Could not find a declaration file for module 'slim-select'. '/Users/jack/Code/monkeytype/node_modules/slim-select/dist/slimselect.js' implicitly has an 'any' type.
  There are types at '/Users/jack/Code/monkeytype/node_modules/slim-select/dist/index.d.ts', but this result could not be resolved when respecting package.json "exports". The 'slim-select' library may need to update its package.json or typings.ts(7016)

which said there are type definitions but could not be resolved due to the exports property. I decided to have a look and the types key was defined incorrectly (im pretty sure the * syntax cannot be used inside the "." key). I updated the path to ./dist/index.d.ts and everything works great.

I also added a ./* export which allows you to import any of the other types like so:

Fully resolves #462
