Working Joe Apollo Announcement (#4395)

# About the pull request

Followup from #4373, Working Joe spawn announced via APOLLO

# Explain why it's good for the game

While it is true that we don't really need a shipwide announcement for
WJs, there are many good reasons to have it at least be on APOLLO
instead (logged, other WJs know, etc), also this was requested from
other PR.
