GNU xargs has a `-r, --no-run-if-empty` option but I don't think we want
to depend on GNU (thanks, MacOS).
Why? Sometimes, when you are messing with codegens, you end up with an
empty input and then it just hangs.

`BeTrue` without explanation in `Should` just prints "false is not true", which
isn't a useful failure message. Even with an explanation that message is still
printed, which is just noise. The new BeTrue/FalseBecause avoid that by
requiring that an explanation is provided and using that instead of "false is
not true".
In Kubernetes, we can enforce the usage of those better alternatives or the
if+Fail combination via forbidigo. Because we have existing code which still
needs to be updated, this can only be a hint for now.
Some examples found with this:
ERROR: test/e2e/apimachinery/protocol.go:75:20: use of `o.BeTrue` forbidden because "it does not produce a good failure message, use BeTrueBecause with an explicit printf-style failure message instead or plain Go: if ... { ginkgo.Fail(...) }" (forbidigo)
ERROR: o.Expect(ok).To(o.BeTrue())
ERROR: ^
ERROR: test/e2e_node/unknown_pods_test.go:163:52: use of `gomega.BeTrue` forbidden because "it does not produce a good failure message, use BeTrueBecause with an explicit printf-style failure message instead or plain Go: if ... { ginkgo.Fail(...) }" (forbidigo)
ERROR: }, f.Timeouts.PodStart, f.Timeouts.Poll).Should(gomega.BeTrue())
ERROR: ^
The solution might also be to write a custom matcher, but that is a bit hard to
explain in the forbidigo message.
This script relies on Go but doesn't set up the private Go environment
(which ensures that the go command meets k/k's requirements). This
fixes that.
As a drive-by improvement, drop two unnecessary backslashes from
regexes (before / which doesn't need to be escaped).

The new zapr adds support for slog. The new zap has various improvements. It no
longer depends on go.uber.org/atomic which enables dropping it from the
Kubernetes dependencies. github.com/pkg/errors is also no longer needed.
