by Oliver Smithansible: update build5-obsworker ssh key
I've reinstalled the build5-obsworker lxc after first upgrading to
openSUSE 15.6 and then discovering that the lxc version is incompatible
with obs-build: 15.6 doesn't have lxc 4 anymore, but a higher version is
not supported by obs-build. I've added a big warning in the wiki so we
don't run into this again until obs-build has been adjusted.
