build: set lambda to log as JSON (#3362)

### Motivation

since the end of 2023, lambda functions can now output JSON as their
logging format, since all of our other logs are structured move to JSON
logs for everything

### Modifications

Convert lambda functions to log as JSON


### Verification

Need to verify everything is working correctly after deploy, eg
alerts/log shipping
