date: clarify --date=raw description

"... in the internal raw Git format `%s %z` format." was clunky in
repeating "format" twice, and would not have helped those who do not
immediately get that these are strftime(3) conversion specifiers.

Explain them with words, and demote the mention of `%s %z` to a
hint to help those who know them.

`--date=short` shows only the date, but not the time, in `YYYY-MM-DD` format.

`--date=raw` shows the date in the internal raw Git format `%s %z` format.
`--date=raw` shows the date as seconds since the epoch (1970-01-01
00:00:00 UTC), followed by a space, and then the timezone as an offset
from UTC (a `+` or `-` with four digits; the first two are hours, and
the second two are minutes). I.e., as if the timestamp were formatted
with `strftime("%s %z")`).
Note that the `-local` option does not affect the seconds-since-epoch
value (which is always measured in UTC), but does switch the accompanying
timezone value.
