description:
Cherry pick the important changes from tzdata2031b:

        Samoa (Pacific/Apia) has cancelled summer time this year
                (change effective last Sunday).
        Jordan (Asia/Amman) has moved the start of summer time from
                the last Thu/Fri in March to the last Thu/Fri in Feb
                to begin next year (2022).

Some more of the non-controversial (and less important, mostly some
corrections to historical data) changes may follow soon.
