IReadOnlyDictionry is not a list type

[clangelov]

This is one is more or less extending a previous PR:
#262

There we changed the ReflectionExtensions so
IDictionary and IDictionary<,> are not regarded as ListType
unfortunately we left over the board IReadOnlyDictionary<,> which also should not be regarded as ListType

is see that limitation over here: https://github.com/graphql-dotnet/conventions/actions/runs/12904851082/workflow
