PR Summary

• Update of Communication Channel in Project Metadata
  The project's dependency descriptor, composer.json, was updated: we switched the information about our IRC communication channel from the old location irc://irc.freenode.net/yii to the new one ircs://irc.libera.chat:6697/yii. This change makes sure interested people or contributors are directed to the right place to discuss the project.
