fix(golang-github-task-slim-sprig): stabilize arm64 rounding

Go 1.26 may fuse the multiplication passed to math.Modf on arm64, changing the fractional result and failing TestRound.

Force an explicit float64 rounding step before math.Modf, as recommended in golang/go#77657, while keeping the original test intact.
