Ask ResearchSeminars to allow automatic adding without manual confirmation

The talks seem to be added for review on ResearchSeminars correctly, I think we can request opening this up.

I see a 401 here: https://github.com/virtualscienceforum/automation/runs/3021323790?check_suite_focus=true (that's speakers' corner)

Interesting, I just tested the code explicitly on another seminar series ('vsfspeakerscornertest') and that works flawlessly. Could it be an access issue for the account [email protected]?
I, for example, cannot post talks to 'speakerscorner' (permission denied). In my account, I can indeed not manage that list like I can for the LRC.
