update github actions for node@20

[graue]

where are these actions defined?

[Andykmcc]

they are all public actions defined by either github or docker. so actions/checkout@v4 can out found at https://github.com/actions/checkout. The same pattern applies to all of them.

[graue]

which one makes the build use Node 20?

[Andykmcc]

scroll down to the Annotations section here. https://github.com/bikehopper/bikehopper-ui/actions/runs/7719972371

[graue]

I see. So this is not about using Node 20 to build or run bikehopper-ui, but upgrading the version of Node used within the implementation of those actions. (correct me if I'm wrong)

[Andykmcc]

that is my understanding.

this change will need to be applied to all of our repos that make a container. maybe others too
