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.
