Fix intro-to-module-scripts.md having a mixup (#1067)

## Changes

<!-- Please summarize your changes. -->
to be specific, it says to create a ModuleScript in ServerStorage, but
it is previously stated that they are commonly placed in
ServerScriptService, so this fixes it
<!-- Please link to any applicable information (forum posts, bug
reports, etc.). -->
No links are needed, as the file and image right below the line I
changed both state that it should be in ServerScriptService
