Default Mediator configuration break Scoped services

[Pycnomerus]

Describe the bug
when using the library default, if you register anything that will be used by a command as scoped.
the application crash. with an impossible to resolve configuration error.

this will probably also break typed httpclient.

To Reproduce
Steps to reproduce the behavior:
when using mediator default registration
register a scoped service.
try to use it inside any IRequest object.

Expected behavior
all type of scopes registration should work without changing the default behaviour.
this is especially a concern since it's not an expected behavior, and introduce risk namely to use Typed HttpClient

Additional context
here's a test sample project to reproduce

The workaround is to set the lifetime to Scoped instead of the default Singleton

builder.Services.AddMediator(configure => configure.Lifetime = ServiceLifetime.Scoped, typeof(Program).Assembly);

It would be nice to re-evaluate the default Lifetime value. It has been set to Singleton for performance reasons. I'm not sure how many projects would be impacted by this change.
