The dialog was pinned to 450px tall with the description in an Auto row, which
was fine for the two-line generic text but not for a message that names the
file, the version it has, the version it needs and the recovery steps: the
description pushed the exception box, the report instructions and the OK button
out of the window.
Cap and scroll the description, give the window room to grow, and top-align the
icon so it stops overlapping the text.
The Classic equivalent, MessageBoxLib.ShowAdminAlert, may need the same and
cannot be checked here.
