Misleading error message for remove explicit elided lifetime

Code

This branch has a compile error: https://github.com/UkoeHB/bevy_cobweb_ui/tree/elided_lifetime

Current output

return type references an anonymous lifetime, which is not constrained by the fn input types
lifetimes appearing in an associated or opaque type are not considered constrained
consider introducing a named lifetime parameter

Desired output

It should point to the `Reader<'_>` and tell me to remove `<'_>`.

Reproduce the compile error from the linked elided_lifetime branch with rustc 1.79.0, then trace the diagnostic for the Reader<'_> return type. Compare the emitted span and suggestion with the desired output; done means the diagnostic points to Reader<'_> and recommends removing <'_>.
