doc: Add installation instructions for ArchLinux

[jdecourval]

Hi,

For my own needs, I created a PKGBUILD to install TandoorRecipes on my ArchLinux based server. I've been using the package for several months by now, and at least one other user tested it: https://aur.archlinux.org/packages/tandoor-recipes-git#comment-924573

On ArchLinux, this package results in something similar to the manual instructions, but is easier to use, and should be more robust, since pacman can track installed files.

Are you interested in linking to this PKGBUILD, or to have it fully merged to this repository? For now, I'm proposing a new documentation page, but the package's sources are still hosted both on the AUR, and on my GitHub.

Let me know what you think of this. I can update the doc, or the package, to your requirements.

looks good to me! I think having it linked is good, it signals a certain degree of legitimacy while also "warning" that it isn't officially maintained.

If you want you can link the feature page in the mkdocs config so its shown in the nav and please add a small "community contributed" warning on top so that people know that the docs might become stale at some point, other than that I think its ready to be merged.

Thanks for your review.

I added my instructions just before "Manual" in the menu, borrowed the warning from unraid.md, signed the CLA, and rebased.
