Show package outputs (#419)

As mentioned in [^1] this PR includes a bump in swap size of the github action evaluating nixpkgs.
This is subject to change once a tentative change to Nix is merged.

* flake-info: use packages-config.nix straight from nixpkgs

No need to override anything anymore, see discussion at
https://github.com/NixOS/nixos-search/pull/343#issuecomment-1021147104

* flake-info: query package outputs

`package_outputs` is now set to the actual outputs of the derivation
instead of `meta.outputsToInstall`

Also updates nixpkgs to get Rust 1.57 which has HashMap.into_keys

* frontend: show package outputs

* Drop 21.05 channel

* Increase swap space in import-nixpkgs worker

* Bump VERSION

* frontend: improvements and refactoring

- move licenses to the end (without a line break)
- pluralise "Licenses:" conditionally
- change the homepage emoji from a house to a world
- replace backwards List.append pipelines with ++ chains
- avoid text nodes in <ul> outside of <li>
- improve rendering of maintainers

* frontend: sort package outputs
