Bug: No difference between days of the selected month vs days of the outside months.

[hpdganesh]

Bug description

When showOutsideDays is enabled, visually there is no difference between days of the selected month vs days of the outside months. Can we add styles to differentiate between actual days vs outside days

To reproduce

Fork this CodeSandbox: https://codesandbox.io/s/react-daypicker-forked-zxj1uc with the code to reproduce the issue.

Steps

1.When showOutsideDays feature is enabled, outside days of the months looks no different than the selected month. This can cause some confusion to the user
2. Render DayPicker with showOutsideDays option

Expected behavior

If we add style to differentiate the days for outside month, users can find the difference between the selected month days against the outside days

Expected behaviour

Additional context

To fix this, we can add opacity as 0.5 for rdp-day_outside class
