[BUG] icalendar export fails with SCHEDULED/DEADLINE entries [9.5.2 (9.5.2-gbc8c3e @ /home/eliza/.emacs.d/straight/build/org/)]

Hello,

It seems like `org-icalendar-export-to-ics' fails to consider the
SCHEDULED and DEADLINE properties. Consider the following org file
`foo.org':

* foo
SCHEDULED: <2022-02-15 Tue>

When invoking `org-icalendar-export-to-ics', we get the following
`foo.ics' file.

BEGIN:VCALENDAR

X-WR-CALNAME:test
PRODID:-//Eliza Velasquez//Emacs with Org mode//EN
X-WR-TIMEZONE:PST
X-WR-CALDESC:
CALSCALE:GREGORIAN
END:VCALENDAR

As you can see, there is no entry for `foo'. Changing the file so that
the timestamp is in the body rather than the SCHEDULED property (though
I'm not sure "property" is the correct term here, given that it's not a
PROPERTY)...

* foo
<2022-02-15 Tue>

...exports as expected.

I noticed this when trying to use org-caldav, and it seems some others
have run into this issue as well. At least, I'm pretty sure the two bugs
are caused by the same issue.

Dear Eliza,

By default, SCHEDULED and DEADLINE are properties of "tasks", i.e. TODO
items, not appointments (aka calendar entries).  Scheduled says when you
intend to start working on a task and deadline is when it needs to be
done by.

In any case, check out the values of org-icalendar-use-deadline and
org-icalendar-use-scheduled which should allow you to do what you want.
