eldritch horrors f5aa5b6815 releng: add releaseTests flake output, test script
this is supposed to be a set of outputs we want to always succeed for
releases. sadly we can't add nixos installer tests using lix to these
because the nixos test framework does not allow overriding nix in the
installer test suites due to unfortunate oversights in the framework.

Hey there!
If you're thinking of working on Lix, please consider talking to us about it!
You should be aware that we are ${sgr}1mnot${sgr}0m accepting major features without some conditions,
and we highly recommend looking at our freeze status page on the wiki:
${sgr}32m${freezePage}${sgr}0m
We also have an overview of the codebase at
${sgr}32m${codebaseOverview}${sgr}0m,
and other helpful information on the wiki.
But above all else, ${sgr}1mwe want to hear from you!${sgr}0m
We can help you figure out where in the codebase to look for whatever you want to do,
and we'd like to work together with all contributors as much as possible.
Lix is a collaborative project :)
You can open an issue at https://git.lix.systems/lix-project/lix/issues
or chat with us on Matrix: #space:lix.systems.
(Run `touch .nocontribmsg` to hide this message.)
