Fix Stream spec format string for P4 versions prior 2020.2

[microdee]

The spec format string for P4 versions prior 2020.2 shouldn't have contained Components field, this caused a runtime error manifested in a format-parameter-argument-count mismatch, when ParentView was None.

Suggestion outside the scope of this PR
To avoid such errors in the future, it is safer to use interpolated raw-string-literals introduced in C# 11:

                value = $"""
                        Stream:	{Id}

                        Update:	{FormBase.FormatDateTime(Updated)}

                        Access:	{FormBase.FormatDateTime(Accessed)}

                        Owner:	{OwnerName}

                        Name:	{Name}

                        Parent:	{ParentPath}

                        Type:	{Type}

                        Description:
                        	{descStr}

                        Options:	{_options}

                        Paths:
                        	{pathsView}

                        Remapped:
                        	{remappedView}

                        Ignored:
                        	{ignoredView}

                        {customFieldsString}
                        """;

Or if C# 11 is not feasible for this codebase then C# 6 interpolated string literals are also better for this purpose.
