circe-network-defaults : correct libera nickserv mask and challenge

[aagon]

The previous nickserv mask and challenge RE did not match correctly with the libera NOTICE, so automatic nickserv identification did not work. After analysing the raw output using irc-debug-log, I found that the RE I provided work (the challenge could be improved).

Feel free to ask questions or offer suggestions.

Best,

Aymeric

Thank you!

I have added :nickserv-identify-challenge "\C-b/msg\\s-NickServ\\s-IDENTIFY\\s-\\S-+\\s-<password>\C-b" in my entry for libera.chat in circe-network-options. That is more in line with the Freenode definition. You could also think about switching the Freenode definition to "This nickname is registered" for orthogonality.
