Rollup merge of #122160 - jieyouxu:eager-translate-help-use-latest-edition, r=cjgillot

Eagerly translate `HelpUseLatestEdition` in parser diagnostics

Fixes #122130.

This makes me suspicious of these other two usage of  `add_to_diagnostic()`. Would they *also* crash? I haven't attempted to construct test cases for them.

```
compiler/rustc_parse/src/parser/expr.rs
3453:            errors::HelpUseLatestEdition::new().add_to_diagnostic(e);

compiler/rustc_hir_typeck/src/expr.rs
2603:            HelpUseLatestEdition::new().add_to_diagnostic(&mut err);
```

This also seems like a footgun?
