Michael Howell a5b639dc01 diagnostics: remove inconsistent English article "this" from E0107
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.

// A few contrived examples where lifetime should (or should not) be parsed as an object type.
// Lifetimes parsed as types are still rejected later by semantic checks.
