useLocalStorage Type detection bug (#409)

mmdHasan-yazdanPanah · web-flow · commit b25df79d776a · 2021-04-26T04:12:17.000+08:00
in my vs code it detects that the type of soredValue is (T | (value: T | ((val: T) =&gt; T)) =&gt; void)
but it must be just (T)
so it throws error 
with this change it solved.
