Openverse weekly update posts publish when no activity occurred

[desrosj]

I noticed today that the weekly automatic summary posts on the Make Openverse blog are published even when there has not been any new activity.

When no closed or merged activity is found, no post should be published.

The team also seems to be inactive. Almost every change in the last year has been related to dependency updates being merged. The posts should likely just be disabled.

I’m unsure if this script is used by other make teams, but if so, this will likely present there as well (there has just been more activity elsewhere). But could be good to fix this script before disabling it so it won’t reoccur if/when it’s turned back on.
