Description
Sometimes EF (or other libraries) wrap database errors. The exception filter should account for this, but was not doing. This was revealed by dotnet/efcore#25050 where we started treating more error numbers as transient and hence wrapping their exceptions.
Note that the original Diagnostics.EFCore.FunctionalTests have a test for this, but it appears that these tests were never updated when the mechanism was changed in .NET 5.
Customer Impact
When first creating a site and the DB doesn't exist, you get an error message rather than the custom database page that allows you to create it.
Regression?
Regressed since RC1, as EF started wrapping more exceptions in dotnet/efcore#25050
Risk
Just falls back to
InnerException
if the exception isn'tDBException
