docs(quickstart): should create namespace before apply yaml files

[Okabe-Rintarou-0]

In quickstart, if we directly apply yaml files, it will raise namespace-not-found errors. It'd be better if we add create namespace command.

Thanks for your participation. FYI, if the namespace can be automatically created when the YAML is applied, better user experience may be provided. You can add the YAML created the namespace in the kmesh code repository, for details:

apiVersion: v1
kind: Namespace
metadata:
   name: kmesh-system
