PHP 8.1 - Uncaught TypeError: Dapr\Client\DaprHttpClient::tryDeleteStateAsync()

Getting the above type error when invoking DaprClient->deleteState().

The implementation for this in Dapr\Client\HttpStateTrait calls deleteStateAsync which in turn calls tryDeleteStateAsync - triggering the error. This is caused by tryDeleteStateAsync requiring an eTag, which is defined as a string and isn't nullable - yet null is passed in this instance.

There are some other type errors in that file too but in my scenario I've only run into the issue with deleteState. The workaround seems to be to used only the tryDeleteState functions, and provide an eTag.

Updating the definition of tryDeleteStateAsync to have string $etag = null, solves the problem and appears to be the intended definition.
