Fixes #88844. A suggested fix is already included in the error message for E0412, so with my changes, E0071 is simply not emitted anymore if the type in question is a "type error". This makes sense, I think, because we cannot confidently state that something is "not a struct" if we couldn't resolve it properly; and it's unnecessary to pollute the output with this additional error message, as it is a direct consequence of the former error.
I have also addressed the issue mentioned in #88844 (comment) by changing the fixed example in the documentation to more closely match the erroneous code example.
