2. How was this tested:

built & started docker with OIDC auth setup -> went through login flow. Verified that changing TEMPORAL_AUTH_SCOPES results in changes in docker.yml

docker run \
    --network host \
    -e TEMPORAL_ADDRESS=127.0.0.1:7233 \
    -e TEMPORAL_UI_PORT=8080 \
    -e TEMPORAL_AUTH_ENABLED=true \
    -e TEMPORAL_AUTH_PROVIDER_URL=https://accounts.google.com \
    -e TEMPORAL_AUTH_CLIENT_ID=xxx \
    -e TEMPORAL_AUTH_CLIENT_SECRET=yyy \
    -e TEMPORAL_AUTH_CALLBACK_URL=http://localhost:8080/auth/sso/callback \
    -e TEMPORAL_AUTH_SCOPES=openid,email,profile \
