[pypy-dev] New official IRC channel

Following the example of many other FOSS projects, the PyPy team has decided to move its official #pypy IRC channel from Freenode to Libera.Chat: irc://irc.libera.chat/hpy The core devs will no longer be present on the Freenode channel, so we recommend to join the new channel as soon as possible. https://www.pypy.org/posts/2021/05/pypy-irc-moves-to-libera-chat.html
