Subject: [PATCH] Don't `use std::opsIndex`, used only when `"validate"` is on.
 (#2383)

In `src/valid/expresion.rs`, use the full path `std::ops::Index` when
implementing the trait on `ExpressionTypeResolver`. This
implementation is `#[cfg(feature = "validate")]`, so the `use`
directive becomes unnecessary when that feature is not enabled,
triggering warnings.
