The chat message from the /random command says "between 1 and 6" instead of "1 to 6"

Summary:
The chat message from the /random command has a mistake. If you for example generate a random number from 1 to 6, it says "between 1 and 6", which would mean the game rolled from 2 to 5, which isn't true. It should say "1 to 6" and not "between 1 and 6".

Steps to reproduce:

1. Enter the command:

   /random roll 1..6

Observed results:
The message says "between 1 and 6".

Expected results:
The message says "1 to 6".
