Merge #778: Change freenode to libera

137e529 Change freenode to libera (W. J. van der Laan)

Pull request description:

  Update website for the change of IRC servers. Change occurences of freenode in active (non-historical) documents to libera.chat. As libera has no official webchat, change the references to their main page for now.

 excerpt: Where to find official information about Bitcoin Core and how you can interact with other Bitcoin Core users and developers.

 Initially, bitcoin.org was used to host the original Bitcoin paper and became the homepage for the [Bitcoin program](https://bitcoin.org/en/download). The site evolved into a general educational resource for Bitcoin, and is [not affiliated](https://bitcoin.org/en/bitcoin-core/about-site) with the modern Bitcoin Core project. The Bitcoin Core project's official website is bitcoincore.org and while other websites continue to host information about Bitcoin Core, their views do not represent Bitcoin Core. We know that the Bitcoin ecosystem can be confusing, and we are working hard to make these relationships more clear.
 
-For development work, Bitcoin Core mainly uses the `#bitcoin-core-dev` IRC channel on Freenode, [Github](https://github.com/bitcoin/bitcoin), and [the bitcoin-dev mailing list](http://lists.linuxfoundation.org/pipermail/bitcoin-dev/).

 While there are many forums in which the Bitcoin community and, indeed, Bitcoin Core contributors engage, Bitcoin Core is not responsible for those forums or their policies, nor does Bitcoin Core take official positions on the community's decisions to use them. Still, we believe it is critical that the Bitcoin community be able to freely discuss and critique every aspect of Bitcoin.
