Don't remove `[]` from type names

[sdwheeler]

Summary of the new feature / enhancement

During initial design work with Jim we decided that we should remove the [] from type names in the INPUTS and OUTPUTS section of CommandHelp. See the following code.

platyPS/src/Transform/TransformBase.cs

Lines 99 to 110 in 33b90b4

	// We don't want to return any arrays, so trim the last "[]" if it is found;
	// We can also simplify the string if desired.
	private string GetAdjustedTypename(Type t, bool simplify = false)
	{
	string tName = simplify ? LanguagePrimitives.ConvertTo<string>(t) : t.FullName;
	if (tName.EndsWith("[]"))
	{
	tName = FixUpTypeName(tName);
	}
	return tName;
	}

Proposed technical implementation details (optional)

Remove the code that removes the [] from the type name.

After further review of existing content, there are cases where it can be important to distinguish between input that can take a collection and also take a singleton on a different parameter. For example, Find-Script has 4 parameters that can take pipeline input for string values.

(gcm Find-Script).Parameters.Values | where {$_.Name -match 'Name|Version$'} | select name,parametertype

Name            ParameterType
----            -------------
Name            System.String[]
MinimumVersion  System.String
MaximumVersion  System.String
RequiredVersion System.String

Tested @adityapatwardhan latest test build (cherry picked). That version is adding the type twice (with and without []) and OUTPUT types are missing [].
