Make CI work (#8057)

* Use export GOPROXY=https://goproxy.cn before build

* Add go version to generate command

* Reproduced the entire build procedure - see notes

I've used:

sudo go clean -i -r -cache -testcache -modcache
make clean
make generate
make golangci-lint
make revive
make swagger-check
make swagger-validate
make test-vendor            <--- this now fails
make vendor                 <--- this now produced changes
git commit -a               <--- this commit

* Add fix from #8059 to complete CI tests
