Pull request overview

This PR updates Clippy diagnostics and UI test expectations. While the PR description focuses on fixing a grammatical issue in the lint_groups_priority suggestion text, the diff also includes a behavioral change to the redundant_closure_for_method_calls lint in eta_reduction.

Changes:

• Add a missing comma in the lint_groups_priority diagnostic suggestion text.
• Update the corresponding ui-cargo/lint_groups_priority .stderr expectations.
• Suppress redundant_closure_for_method_calls suggestions when the method comes from an “ambiguous” crate name (multiple loaded crates with the same name).
