Remove alterId field

VmessQRCode "aid" is kept for backwards compatibility and always set to 0
Since 2022, new *ray server will reject alterId > 0.
If it is enabled and set specifically > 0, for v2fly server v4.28.1+ and Xray server v1.0.0+, client with either 0 or above 0 can connect
For older v2ray server, the default config will not work, user has to use custom config to set alterId. This is NOT recommended for security reason
