Documentation: NGINX Open Source Alpine installation documentation uses apt-get for Step 4 rather than apk

[Moro-Code@…]

I was not sure where to report this. I spoke to members of the IRC chat that directed me to here. In [step 4](​https://docs.nginx.com/nginx/admin-guide/installing-nginx/installing-nginx-open-source/#installing-a-prebuilt-alpine-linux-package-from-the-official-nginx-repository) of the installing pre-built binaries for NGINX Open Source, the commands given use apt. The package manager for alpine linux is apk and not apt. So these are incorrect commands and might confuse users into thinking they need to install the apt package manager for alpine.

Thanks for catching this. Correct instruction can be found at the official nginx.org page here:

​http://nginx.org/en/linux_packages.html#Alpine

Relevant instructions in the Admin's Guide seems to contain extra / unneeded "4. Install NGINX Open Source:" step with incorrect instructions, likely accidentally copied from other OS instructions. Yaroslav is going to fix this.
