Hi @cclauss, thank you for this PR, however I'm not really interested in adding Dependabot. It has pretty bad habits and a history of spamming open source projects. It's also overkill for a very slow-moving repo like this one. Having weekly or even monthly bot commits would mean ~50% of all PRs being from bots, and that's usually a bad sign and too much churn.

Patterns * means that there can only be one pull request open at a time. GitHub Actions rarely receive major upgrades. Monthly means a theoretical maximum of 12 PRs a year (only one at any given time) and probably much less.

Hi @cclauss, I was adding this too in the meanwhile on a working branch of mine, when I happened to notice your PR – @rgommers, I would suggest getting this in so that we can have updates for GitHub Actions, now that we will be pushing nightly wheels soon (#706, https://github.com/scientific-python/upload-nightly-action/issues/75).

I would be happy to be assigned for review on such PRs. We could enable the rebase option as well in case that can help keep a single PR clean.

P.S. I was initially adding it on a daily cadence (I like that personally), but having it monthly would be perfectly fine.
