Consider `tests/ui/const-generics/generic_const_exprs/issue-102768.stderr`, the error message where it gives additional notes about where the associated type is defined, and how the dead code lint doesn't have an article, like in `tests/ui/lint/dead-code/issue-85255.stderr`. They don't have articles, so it seems unnecessary to have one here.
