fix(lint): nolint modernize on backward loop in it.Reverse

[headless-samber]

The modernize linter (golangci-lint v2.12+) flags the backward loop in it.Reverse as replaceable with slices.Backward.

However, slices.Backward was introduced in Go 1.24, and lo supports Go 1.18+. This adds a targeted nolint directive with an explanation.
