[6.0.x] Fixed #31506 -- Clarified that ExpressionWrapper does not perform
database casts.
Added warning in DateField documentation about type differences when using
timedelta on PostgreSQL and MySQL. Mentioned Cast() and integer arithmetic
solutions.
Backport of 55af4749b9a48b2978e893e7d7be313c0b2abdb1 from main.
