Fix golang actions

- add manual scanning of github keys, it is required since
  webfactory/ssh-agen `v0.8.0` S. https://github.com/webfactory/ssh-agent/releases
- remove hard-coded golang version, always build with the one from
  `go.mod`. Note: it requires the checkout to be done *before* setting
up the go action, otherwise the version cannot be determined, obviously
- bump golangci-lint version to `v1.53.3`. `v1.50.*` is not compatible
  with golang `1.20`, s. golangci/golangci-lint#3420
