Fix bug: Yggdrasil client can't send message upper 22w17a

Browse source 
When try to send message in yggdrasil-auth server with `enforce-secure-profile=true`
and `online-mode=true` enabled, will fail with message in red:
Chat disabled due to missing profile public key. Please try reconnecting.
So yggdrasil-auth-client also has to encrypt chat messages like Microsoft-auth-client
to send out messages.
