lib.ts: adjust status logging levels

GitHub reports when workflow runs log messages with `notice` or higher
logging levels, e.g.:

> There are 0 failures, 0 warnings, and 1 notices.

Since `notice` was being used regardless of status, these reports were
misleading, because everything was working correctly on successes and 
no-ops.

Therefore, the successes and no-ops now only log with `info`, and the 
failures now only log with `error` (which is perhaps more appropriate
than `notice` for errors).
