Part of #229910.
Unfortunately this is a little hacky because upstream doesn't intend to
support it for 2.5, but only for 3.0 which isn't out yet, however nodejs-16
will get out of maintenance during the support-span of NixOS 23.05[1].
The only breaking change is that `extract-files` uses a deprecated way
of exposing modules, I went through the list of other breaking
changes in v17 and v18[2][3] and couldn't spot any usage of removed
features, also local testing didn't reveal further issues.
Unfortunately fixing that breakage turned out to be non-trivial.
Currently, `extract-files@9.0.0` is used with the problematic portions
in its `package.json`, however it's only a transitive dependency of
`@graphql-tools/url-loader` & `apollo-upload-client`. Unfortunately, the
versions of that in use require v9 and don't work with a newer version of
`extract-files` with the problem fixed[4]. Also, upgrading the
dependencies in question is not a feasible option because `graphql-tools`
was split up into multiple smaller packages in v8 and also some of the
APIs in use in `wiki.js` were dropped there[5], so this would also be
very time-consuming and non-trivial to fix.
Since this was the only issue, I decided to go down the hacky route and
patch the problem in `package.json` of `extract-files` manually during
our `patchPhase`.

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './public/extractFiles' is not defined by "exports" in /wiki/node_modules/extract-files/package.json

Currently systemd-ask-passwd times out after 1m30s. After 3 tries this
causees systemd to enter the emergency shell and basically lead to an
unbootable system requiring a reboot to be able to try to unlock again.
Also if a pool is imported but not unlocked, the unlock step will no
longer be skipped.
Enable using an erofs filesystem as one of the filesystems needed to
boot the system. This is useful for example in image based deployments
where the Nix store is mounted read only.
[erofs](https://docs.kernel.org/filesystems/erofs.html) offers multiple
benefits over older filesystems like squashfs. Skip fsck.erofs because
it is still experimental.
Calling `eval-config.nix` without a `system` from a Nix flake fails with
`error: attribute 'currentSystem' missing` since #230523. Setting
`system = null` removes the use of `currentSystem` and instead uses the
value from the `nixpkgs` module.
Note that this does not add to the `forbiddenDependenciesRegex`
code because that code check should be unaffected as it only checks
output dependencies, not build dependencies.
Build deps are added after that check, if those are enabled in the
first place.
