For debug builds, WSManReceiveDataResult.Unmarshal hits a Dbg.Assert due the result data type being marked as Text instead of Binary (see https://github.com/PowerShell/PowerShell/blob/6febd1f8831ec4ab2127c4fef934484eb2ca374f/src/System.Management.Automation/engine/remoting/fanin/WSManNativeAPI.cs#L1937)

When debugging, the data is, in fact, binary and release builds work as expected since it doesn't validate the date type.

The impact is debug builds of PowerShell Core cannot be used with PSRP/Linux.
