Adjust Activity Pub configs to include dripline and cosmos

[tripledoublev]

Making progress on the Activity Pub integration;

• ✔️ AP Inbox creation success
• ✔️ Github action commits _data/activity_pub.yml

I noticed in the commit linked above that the notifications only include Hypha Does Cosmos.
I believe this is due to incomplete settings in _config.yml

• Fix _config.yml to include Dripline posts
• Consider renaming the inbox to HyphaCoop instead of Dripline to include all activity under one account

Question;
Would it be preferred to create two accounts and keep notifications separate for Dripline and Hypha Does Cosmos

We can test this when hyphacoop/social.distributed.press#15 is implemented, because you'd need two actors (ie @dripline@hypha.coop and @cosmos@hypha.coop)
