Rename authorization server artifact to jmix-authserver

[gorbunkov]

Currently the artifacts coordinates are:

• io.jmix.authserver:jmix-authorization-server
• io.jmix.authserver:jmix-authorization-server-starter

Artifact names should follow other jmix add-ons naming conventions and should be:

• io.jmix.authserver:jmix-authserver
• io.jmix.authserver:jmix-authserver-starter

Directory names and application properties names should also be renamed.
