feat(theme): Move indexSelector styling to default.css

BREAKING CHANGE: Classes are now named `ais-index-selector` and
`ais-index-selector--item` to stay consistent with other widgets.

Updated tests as well. Widget is responsible for adding default
classes + user-defined ones. Then component simply add them to the
markup.
