Allow docs build on schedule

[Ianlmgoddard]

Would it be possible to allow doc deploys on schedule jobs? Currently the only events that trigger a docs build are push or `workflow_dispatch.

My use case: I have some examples in my package docs that pull and plot recent data, I think it would be nice if the docs had up to date plots. One possible way to do this is to set up the docs job to run on a schedule (via a github action), however this doesn't trigger a docs build because schedule events don't trigger builds.

Maybe a kwarg could be added to deploydocs? so the user could control which events they'd like to trigger builds.

Sure, do you want to make a patch? Should be roughly equivalent to this patch: 5f452f4

Thanks for getting back to me, opened the PR #1773 (if that's not already obvious from above).

I diverted a bit from 5f452f4, because I thought the user would want control of whether or not to deploy the docs on schedule jobs. Happy to discuss here/on the PR.
