Command argument suggestions for <slot> are not sorted numerically

When <slots> is an applicable suggestion for a command, all the suggestions are sorted by the leftmost number first and foremost instead of numerically

Steps to Reproduce:

1. Enter the following (incomplete) command:

   /item replace entity @p 
   

2. Scroll down through suggestions

Expected & Observed Results:

- The arguments which have more than 10 or more possible numerical values are sorted as `[slot].1` first, then `[slot].10`, then `[slot].2` through `[slot].9`.
- Expected would be `[slot].1` through `[slot].10`.
