Backport of #74261 to release/7.0-rc1
/cc @tarekgh
Customer Impact
In Dependency Injection, when retrieving the IServiceProvider service and disposing it, it will not dispose the parent container which causes a memory leak. Users of HubConnection in SignalR already experienced and reported this issue as indicated in the issue #73832
Testing
Have passed all CI and regression tests. And manually confirmed it fixes the memory leak.
Risk
Fairly low risk. The change started to dispose the Service Provider object that is supposed to be disposed. The break here is minimal as no-one supposes to use this disposed object and even users can use this disposed object to create a Singlton service.
