The fact that the rim didn't split there suggests that the spoke hole support there is now more stress-relieved, so perhaps even better than on the rest of the rim's spoke sockets.

Also considering that the better single-walled rims were designed and made with such cold-formed stress-relieving dimples tells me that this one is no problem at all.

The spoke will now come up slightly long. Adding a pre-cupped washer or perhaps two very thin washers will restore the spoke length issue while further reinforcing the deformed spoke hole.

And, if you're still concerned about the rim's integrity, lace the spokes so that a lower-tensioned, non-driveside spoke fits into the deformed spoke hole.

Possibly the rim's width between the brake pads will now have a slight sort of "high spot" local to the deformed spoke hole, easily pinched down gradually/gently flush using a bench vise.
