Flags incorrect in conformance test documentation

[taragu]

Is this a BUG REPORT or FEATURE REQUEST? (choose one): BUG REPORT

Please provide the following details:

Environment:

Minikube version (use minikube version): v0.30.0

• OS (e.g. from /etc/os-release): macos
• VM Driver (e.g. cat ~/.minikube/machines/minikube/config.json | grep DriverName): virtualbox
• ISO version (e.g. cat ~/.minikube/machines/minikube/config.json | grep -i ISO or minikube ssh cat /etc/VERSION): v0.30.0
• Install tools:
• Others:

What happened:
I tried following the documentation to run conformance tests for minikube with the following commands listed in the documentation:
go run hack/e2e.go -v --test --test_args="--ginkgo.focus=\[Conformance\]" --check_version_skew=false --check_node_count=false
and
go run hack/e2e.go -v --test --test_args="--ginkgo.focus=should\supdate\sannotations\son\smodification" --check_version_skew=false --check_node_count=false

However, the flags --check_version_skew and --check_node_count turned out to be invalid flags.

--check_version_skew should be --check-version-skew. I don't know what the correct flag for --check_node_count is.

What you expected to happen:
Running the commands listed in the documentation should be able to launch the conformance tests without the unknown flag error.

How to reproduce it (as minimally and precisely as possible):
Follow the documentation to run the conformance tests.

Output of minikube logs (if applicable):

Anything else do we need to know:
