[red-knot] MDTests: Do not depend on precise public-symbol type inference (#15691)

Browse Source 
## Summary

Another small PR to focus #15674 solely on the relevant changes. This
makes our Markdown tests less dependent on precise types of public
symbols, without actually changing anything semantically in these tests.

Best reviewed using ignore-whitespace-mode.

## Test Plan

Tested these changes on `main` and on the branch from #15674.
