ci: track github actions with dependabot

[Kakadus]

Just saw some warnings in the latest ci runs, github is deprecating another node version. I never actually saw any practical incompatibilities of actions, so I told dependabot to group all ci PRs for less noise.

I'm a bit confused, I don't see a deprecation warning (I checked out the output of the "Compile SCSS / Setup nodejs" step).
Our workflow definition file in .github/setup_nodejs/action.yml doesn't seem to specify a node version. Where exactly can I find the warning and what version specification are we talking about?

In general, I'm fine with just always running on the latest stable node version. After #2077, we're basically only using node for scss and typescript, both are big enough for that to work I guess.

The warnings I talked about are here if you scoll down. It is related to the node version used to execute the ci step itself. We currently use actions/checkout@v3, actions/setup-python@v4, actions/setup-node@v3 and actions/upload-artifact@3 which are all "deprecated" by github

The warnings are not related to the node version we use (e.g. we could still use an old node version with the new action versions)

Ah sorry, didn't see those. The changes are fine with me then
