Add grouping:

• frequent: for packages that are updated very frequently, so we can delay their merge
• all: for everything else not matching the groups

Add github-actions

ci files

• use the go version from go.mod file
• add govuln check github action

Makefile

• Use go run instead of go install where applicable
• Script for installing golangci no longer needed
• Add govulncheck
• Gather all tool versions in a single place
