Add LOG_CHANNEL to Laravel example

[stayallive]

DESCRIBE YOUR PR

When a user is setting up their log stack in Laravel it isn't a given that the log driver is actually set to "stack" which it needs to be otherwise the existing instructions (setting LOG_STACK ) has no effect. So add the additional env variable to indicate the LOG_CHANNEL should be set to "stack".
