Typo in doc/bird.conf.example2: MB-BGP -> MP-BGP

Hi, In https://gitlab.nic.cz/labs/bird/-/blob/master/doc/bird.conf.example2, the comment says "This is an example configuration file for MB-BGP setting". Shouldn't it be MP-BGP setting? From git blame at https://gitlab.nic.cz/labs/bird/-/blame/master/doc/bird.conf.example2, the commit message says "Doc: Add MP-BGP example config file". It's quite trivial though 😂. Best regards, Hexhu
