Fix name mismatch introduced with #451

[masesdevelopers]

The problem is related to a name mismatch introduced with #451, we don't have introduced yet an automatic test for PowerShell extension.
About your questions:

• KNetPS mainly is a PowerShell wrapper for Apache Kafka command-line commands, plus can be used to create PowerShell scripts
• Some information are available in https://knet.masesgroup.com/articles/usagePS.html
• As stated in KNetPS module Arguments is a string containing the arguments accepted from the Java Main-Class so, in general, you can launch the command (e.g. Start-TopicCommand) and see the help of the command, otherwise you can browse the information available in official Apache Kafka site

The class containing the Launch method is JNetCoreBase

JNet/src/net/JNet/JNetCoreBase.cs

Line 287 in 2cd1256

public static new void Launch(Type type, params string[] args)

Update this line

JNet/src/net/JNetPSCore/JNetPSHelper.cs

Line 497 in 2cd1256

_ = typeof(TClass).RunStaticMethodOn(typeof(JNetCore<TClass>), nameof(JNetCore<TClass>.Launch), type, args);
