Update Embed Order on role update to user

Update the order of embeds in the staff intro channel if one of their role changes

One thing to consider with this is for instances when an admin is playing around and the moderator role is removed from someone for a certain time. Any changes to this shouldn't be atomic and should probably only check for update once a day

If the same admin made the user mod again withiin that 24h timeperiod, their state would have been altered. I think its better to keep updating at every member event

I implemented it to check for that when the user edits their intro. The actual contents don't need to be changed, just when the command is ran.

Is this good to be linked as resolved with the merge of #145 ?
