docs: fix api-trace2 doc for "too_many_files" event

In 87db61a (trace2: write discard message to sentinel files,
2019-10-04), we added a new "too_many_files" event for when trace2
logging would create too many files in an output directory.
Unfortunately, the api-trace2 doc described a "discard" event instead.
Fix the doc to use the correct event name.
