Move eslint-config-prettier to last in extends (#17)

eslint-config-prettier must be last in the extends array so it can
properly override formatting rules from all preceding configs. Being
first meant eslint:recommended and the typescript-eslint config could
re-enable formatting rules after prettier disabled them.
