[I] go/adbc/pkg: the "warn" log level keeps the error level [arrow-adbc]
HyukjinKwon opened a new issue, #4880:
URL: https://github.com/apache/arrow-adbc/issues/4880
### What happened?
In the Go driver template, `case "warn":` has no body, and Go doesn't fall through, so `ADBC_DRIVER_<PREFIX>_LOG_LEVEL=warn` leaves the level at `slog.LevelError` ([driver.go.tmpl#L203](https://github.com/apache/arrow-adbc/blob/ecd98b42118c21547f509a11cc037f2faa902430/go/adbc/pkg/_tmpl/driver.go.tmpl#L203)). `warn` is one of the values the logging help text suggests; `warning` works.
Every driver generated from the template inherits this, including Flight SQL here and the drivers in adbc-drivers, for example [adbc-drivers/spark](https://github.com/adbc-drivers/spark/blob/1532d8043666f5d41f544bb25d3b915c2aebf80b/go/pkg/driver.go#L215).
### Stack Trace
_No response_
### How can we reproduce the bug?
Set `ADBC_DRIVER_FLIGHTSQL_LOG_LEVEL=warn` and load the Flight SQL driver: warnings aren't logged. With `ADBC_DRIVER_FLIGHTSQL_LOG_LEVEL=warning` they are.
### Environment/Setup
Found by reading the source at ecd98b4 (main).
