This commit removes the unnecessary slice copy in `sortEntries`, and
replaces `sort.Slice` [^1] with the new `slices.SortFunc` [^2].
As recommended by the Go documentation, `slices.SortFunc` is generally
faster because it uses generic, whereas `sort.Slice` relies on
reflection, which incurs additional allocations
The benchmark result from the newly added `Benchmark_sortEntries` show
approximately a 64% performance improvement.
Benchmark result:
