In `window_frame_end` Django is currently enforcing that the `end`
argument of `ValueRange` and `RowRange` can't be a negative integer.
However, according to the Postgres documentation, "value PRECEDING" is
allowed for "frame_end", so a negative integer is equally valid for `end`
as it is for `start`.

Duplicate of #29850 which mentions a negative `start` and `end`.
