Upstream change

moved a few fields from `lowdown_opts` toa new `lowdown_opts_term`
struct. As a result the build started failing as:

The change adds version-based conditional to support both pre-1.4 and
1.4 forms of the initialization.
Closes: https://github.com/NixOS/nix/issues/12113
The primitive `readFileType p` has a list of acceptable types, and so does `readDir path`
This edit makes the formatting of the list consistent between themselves, and other parts of the documentation.
Paths are already quoted:
error:
… while fetching the input 'path:/nix/store/rs2s2ca7xs87v82aps54m1p3sqrfz6c8-source'
error: chmod '"/nix/store/rs2s2ca7xs87v82aps54m1p3sqrfz6c8-source"': Read-only file system
src/nix/flake.md describes the format of flake.lock files. Before this
change, it said that the original field was “The original input
specification from `flake.lock`[…]” The original input specification is
in flake.nix, not flake.lock.
When resolving indirect flake references like `nixpkgs` in `flake.nix`
files, Nix will no longer use the system and user flake registries. It
will only use the global flake registry and overrides given on the
command line via `--override-flake`.
Commit cfe66dbec updated `nix upgrade-nix` to use
`ExecutablePath::load().find`, which broke the logic for finding the
profile associated with the nix executable. The error looks something
like:
```
$ sudo -i nix upgrade-nix --debug
found Nix in '"/nix/store/46p1z0w9ad605kky62dr53z4h24k2a5r-nix-2.25.2/bin/nix"'
found profile '/nix/store/46p1z0w9ad605kky62dr53z4h24k2a5r-nix-2.25.2/bin'
error: directory '"/nix/store/46p1z0w9ad605kky62dr53z4h24k2a5r-nix-2.25.2/bin/nix"' does not appear to be part of a Nix profile
```
This seems to happen for two reasons:
1. The original PATH search resulted in a directory, but `find` returns
the path to the executable. Fixed by getting the path's parent.
2. The profile symlink cannot be found because
`ExecutablePath::load().find` canonicalizes the executable path. I
updated find to normalize the path instead, which seems more in line
with how other programs resolve paths. I'm not sure if this affects
other callers though.
I manually tested this on macOS and Linux, and it seemed to fix
upgrading from 2.25.2 to 2.25.3.
