Describe the bug
Wrong default value in the docs

  https://github.com/nginxinc/kubernetes-ingress/blob/main/docs/content/configuration/global-configuration/command-line-arguments.md#-main-template-path-string

• -virtualserver-template-path
  https://github.com/nginxinc/kubernetes-ingress/blob/main/docs/content/configuration/global-configuration/command-line-arguments.md#-virtualserver-template-path-string
