Enable dependabot updates for WB/WS (and group them)

[jeremywiebe]

Summary:

Juan and I were discussing keeping Perseus dependnecies up to date with webapp (especially WB and WS). This is a trial run to see if Dependabot will help us. It should open up a new PR any time WB or WS packages are released. And all WB or WS packages that received an update should be updated together in the same Perseus PR.

Issue: "none"

Test plan:

I suspect I'll need to land this and monitor it to test. Github action infra is notoriously difficult to test locally.

Can we filter out certain packages? I'm asking as we have a couple of WB deprecated packages that we usually skip when upgrading webapp (wb-color and wb-spacing).

It would be nice if we could skip them programmatically with dependabot so we never see these packages in here, as it would be noisy/counterproductive to have them included.

[jeremywiebe]

We don't have any usages of wb-color nor wb-spacing in Perseus today. I can exclude them here, but I think I'm going to add an ESLint rule to ensure it doesn't come back. :)
