Forward log argument from loadEnvConfig to processEnv (#22440)
Forward log argument from loadEnvConfig to processEnv (#22440)

We do have a third argument on `processEnv` to customize the console instance, however `processEnv` relies on `processEnv` which also have the same argument for the same purpose but it's not forwarded from `processEnv`. 

Was there a purpose for it to be left out ? If not I would expect it to be forwarded 😄
