Generated client has wrong namespace for ComparisonHelper

Is there an existing issue for this?

Describe the bug

When using version 13.0.0-preview.93 of StrawberryShake and generating a client from graphql scheme, the generated client has some methods that depend on "ComparisonHelper". These methods has the wrong namespace in the generated code, they refer to global::StrawberryShake.Helper.ComparisonHelper.SequenceEqual(Items, other.Items) when the correct namespace seems to be "Internal", so this seems correct: global::StrawberryShake.Internal.ComparisonHelper.SequenceEqual(Items, other.Items).

Steps to reproduce

1. dotnet graphql generate
2. Open generated client code, check errors.

Relevant log output

Severity	Code	Description	Project	File	Line	Suppression State
Error	CS0234	The type or namespace name 'Helper' does not exist in the namespace 'StrawberryShake' (are you missing an assembly reference?)	Application	".."\Generated\GraphApiClient.Client.cs	1683	Active

Additional Context?

Strawberry Shake

Version

13.0.0-preview.93

Start by reproducing the issue with dotnet graphql generate and inspect Generated\GraphApiClient.Client.cs, especially the reported line and its ComparisonHelper references. Trace the generator or template that emits the namespace, then verify that the generated client compiles and uses the existing StrawberryShake.Internal.ComparisonHelper namespace.
