[DatePicker] Missing exports in lab/index.js

[havgry]

The following components are not being exported in packages/material-ui-lab/src/index.js which seems like a trivial mistake to me. Any thoughts?

ClockPicker (fixed in next)
DateRangDelimiter
DateRangePickerDay
MonthPicker
PickersCalendarSkeleton

Tech	Version
Material-UI	v5.0.0-alpha.16

@havgry Well spotted, any component that has its own folder, so:

• ~DateRangeDelimiter~
• DateRangePickerDay
• MonthPicker
• PickersCalendarSkeleton

are missing. Do you want to submit a pull request to export them? :) We would only need them to be sorted ASC, e.g.:

Regarding DateRangeDelimiter, I think that we should drop it. It can be replaced with <Box sx={{ mx: 2 }} />: #23609.

Small fix, I'll do the PR (without DateRangeDelimiter).
