Fixes #4293

PR Type

What kind of change does this PR introduce?

Bugfix

What is the current behavior?

The debounce extension was incorrectly updating the action in the ConcurrentList.

According to documentation the value passed in the updateValueFactory function, of the AddOrUpdate method, is the current value in the dictionary.

https://docs.microsoft.com/en-us/dotnet/api/system.collections.concurrent.concurrentdictionary-2.addorupdate?view=net-5.0

Therefore the current behavior is maintaining the old action and not updating with the new passed action.

_debounceInstances.AddOrUpdate(timer, action, (k, v) => v);

What is the new behavior?

Changed so that the action in the _ debounceInstances Dictionary is updated with the latest version.
