* docs: NIC+NAP wafv5 install guide perm fix

Closes #7757

* Use `/tmp` folder on both the host and the docker image when compiling
  the waf policy bundle due to file permission handling differences
  between docker engine and docker desktop
* Update the installation guide to reflect the new location of the
  waf policy bundle and downloaded source JSON

* Change the destination of an mv to /Users/g.javorszky/Projects/NIC/kubernetes-ingress-docs instead of .

* Fix a typo for the downloaded file name
