Trigger deployments on automated pushes

#45 was meant to trigger deployments on Netlify on each push to the main branch on this repo. While it works for commits from users, it doesn't work for automated commits, the ones that we really want this to trigger on.

We need to move the deploy job to the schedule workflow (https://github.com/endoflife-date/release-data/blob/main/.github/workflows/update.yml#L65-L69) conditional on the commit being made.
