Copied hash ranges are backwards

**Describe the bug**
I've been using the hash range copy feature introduced in #1288 to do a lot of cherry-picking, a large majority of which are consecutive ranges. However I can't use the range as-is and would have to manually reverse it myself, since marks are sorted by latest first. Thank you!

EDIT(2024/06/28): I've noticed that even for non-consecutive ranges the order is reversed. If the order of marks is not depended on anything else in gitui, I think it's desirable to reverse it for ease of use.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to the Log screen
2. Mark a consecutive range of commits and copy to clipboard
3. Try to `git cherry-pick` with the copied range
4. `error: empty commit set passed`

**Expected behavior**
It would be more convenient for hash ranges to be sorted from oldest to latest.
