[MCL-9562] Launcher logs access token in launcher

The bug

It looks like the launcher logs the access token (auth_access_token) in the launcher_log.txt file.

[0701/165530:INFO:ClientStarter.cpp(625)] ${auth_uuid} == "0fec4f7a6a9b4c43ad1b235e7fbc9822"
[0701/165530:INFO:ClientStarter.cpp(625)] ${auth_access_token} == ###
[0701/165530:INFO:ClientStarter.cpp(625)] ${user_type} == "mojang"
...

This might be problematic if the log file is shared or if another program accesses it.
