PIA region capitalization

[theOriflamme]

I was having a memory leak issue with a stack in portainer (i know i know) and while checking logs i noticed this:
WARN values us mississippi, us louisiana, us east are not in choices
followed by the full list of PIA server regions listed with capitolization US Mississippi, etc

INFO Settings summary:
Regions: us texas, us mississippi, us louisiana, us east

docker-compose.yml:
- SERVER_REGIONS=US Texas, US Mississippi, US Louisiana, US East

I thought this was a portainer issue so I killed it and redeployed the stack with docker compose and everything came up exactly the same in my log.
Note that gluetun is working perfectly with my primary region.
