Modify: change to use onplayerjoincomplete instead of onplayerjoined

In VRChat client version 2024.4.1 (Build 1533), the log file output
format has changed.

https://docs.vrchat.com/docs/vrchat-202441
The above page contains the following text:

> Output logs now include user IDs when players join or leave
> an instance.

Log entries containing "OnPlayerJoinComplete" seem to output the same
as before, so I would change this sample vrchat_join_log2.rb to use
/onplayerjoincomplete/i instead of /onplayerjoined/i.
