deps: Update all backend dependencies

[jkroepke]

Before looking into #41, I would like to start with the lastest dependencies.

First of all, thanks a ton for all the work you made to put up those PRs. I will look into them as soon as I can. They all look great at the first glance. I have some suggestions so that we can discuss them on each PR.

Regarding the curren PR, I have very few minor comments. I think we need to update Validate plugin step as well as it uses the 1.21.x Go as of now.

We are still missing this one. Could you please update it?

Now, the plugin validator breaks...

But it works with the old version.

Can be put the update of the plugin validator to a separat PR?
