Update docker version and buildx version

Fix flaky arm64 emulator issue docker/buildx#542

Use Go 1.17.2 and fix golint installation

fix drone build failure

`go install ginkgo` followed by `which ginkgo` is newly added in the upstream repo.
This is making the drone build fail for arm64 arch. The ginkgo library
gets installed under $GOPATH/bin/linux_arm64 dir. This is unlike amd64 images
which typically install go libraries under $GOPATH/bin. Since the previously mentioned
dir is not in PATH, the command `which ginkgo` fails. I've added this location to PATH
to fix the build failure. See upstream PRs linked below for more info:
kubernetes#8566
kubernetes#8569

use go 1.21.5 | go mod tidy
