PartitionAssignmentStrategy default value is different from the documented one

[3Dmondo]

Description

The default value of PartitionAssignmentStrategy assigned in the StreamConfig constructor is CooperativeSticky see:

streamiz/core/StreamConfig.cs

Line 2321 in 940f098

PartitionAssignmentStrategy = Confluent.Kafka.PartitionAssignmentStrategy.CooperativeSticky;

while in the xml documentation it says range:

streamiz/core/StreamConfig.cs

Lines 1966 to 1971 in 940f098

	/// <summary>
	/// Name of partition assignment strategy to use when elected group leader assigns
	/// partitions to group members. default: range importance: medium
	/// </summary>
	[StreamConfigProperty("partition.assignment.strategy")]
	public PartitionAssignmentStrategy? PartitionAssignmentStrategy { get { return _consumerConfig.PartitionAssignmentStrategy; } set { _consumerConfig.PartitionAssignmentStrategy = value; } }

I did experiment KStream-KTable Join issues with the default CooperativeSticky and setting the option to Range solved the issues (as confirmed by this comment #328 (comment)).
It would be nice to have the documentation aligned with the "real" default (and eventually set the default equal to Range as per above mentioned comment).

How to reproduce

Please provide the following information:

• A complete (i.e. we can run it), minimal program demonstrating the problem. No need to supply a project file.
• A code snippet with your topology builder (ex: builder.Stream<string, string>("topic").to("an-another-topic");)
• Streamiz.Kafka.Net nuget version.
• Apache Kafka version.
• Client configuration.
• Operating system.
• Provide logs (with in debug mode (log4net and StreamConfig.Debug) as necessary in configuration).
• Critical issue.
