chore: add tag name to a11y_click_events_have_key_events warning (#18272)

Ref: https://github.com/sveltejs/svelte/issues/15100

Adds the tag name to the `a11y_click_events_have_key_events` warning
given when a non-interactive element has a click handler but no keyboard
events.
This already happens in `a11y_no_static_element_interactions`, and
should probably happen in many more messages.
