improvement(settings): drop the Delete account row's description (#6845)

The confirmation modal already states the consequence, and states it better:
it names the account, enumerates the workspaces that will be deleted, notes
which billing transfers instead, marks 'This cannot be undone' in the error
color, and requires typing the email to proceed. Nothing is lost by removing
the line from the row.

The wrapper it shared with the row goes too, now that the row is the section's
only child.
