Description

The host is not loading secrets from the user secrets nor from the command line.

Reproduction Steps

https://github.com/devhl-labs/Hosting-6.0-Issue-Repro/blob/daabb5c610c640a76fae9d2bc0391fcc620424db/WorkerService1/WorkerService1/Program.cs#L20

See the repo above, or create a new worker service project. Observe the IConfigurationBuilder sources count be different when using Microsoft.Extensions.Hosting 5.0 and 6.0. Look at the HostBuilderContext.Configuration.Providers and observe that what is missing is user secrets and CommandLineConfigurationProvider.

Expected behavior

The loaded secrets should be the same.

Actual behavior

Missing secrets configurations when using 6.0.
