dependabot supports github actions

[FabianFrank]

https://docs.github.com/en/code-security/dependabot/working-with-dependabot/keeping-your-actions-up-to-date-with-dependabot

might be worth mentioning in the readme?

Yes you are correct. We should add this on the documentation as an alternative.

I can see that the README documents dependabot as an alternative for keeping GHA updated. I am curious: what does this Action do that dependabot won't? The relative advantages or disadvantages are not well documented.
