refactor(components): replace items prop in Grid with children prop

It is easier to read and to maintain this way. The `items` prop was not
useful since we are not manipulating the items. Changes:
* extract GridItem component from Grid component
* replace `items` prop of type Array<ReactNode> with `children` prop of
type ReactNode
* remove GridItem styles
