"Customize WebApplicationFactory" section doesn't work with EF 9.0

[AndriySvyryd]

Description

The approach outlined in https://learn.microsoft.com/aspnet/core/test/integration-tests?view=aspnetcore-9.0#customize-webapplicationfactory no longer works. It was relying on implementation details, see #35126

It is also recommended to use the same provider for testing as the one used in production as they could have drastically different behaviors, see testing against the production database.

The connection / connection string for the same provider can be changed easily:

  services.ConfigureDbContext<TestContext>(options => options.UseSqlite(connection));
