nix-index: breaking change in v0.1.9 backported to NixOS 25.05

[me-and]

Nixpkgs version

• Stable (25.05)

Describe the bug

nix-index v0.1.9 changed the behaviour of the nix-locate command in a breaking way, removing the --top-level argument to make it the default, and adding the --all argument to restore the old behaviour, per https://github.com/nix-community/nix-index/releases/tag/v0.1.9

This is a breaking change, and therefore should not have been backported to 25.05.

Steps to reproduce

With an older 25.05 tree:

$ nix shell github:NixOS/nixpkgs/b43c397f6c213918d6cfe6e3550abfe79b5d1c51#nix-index --command nix-locate --top-level /bin/latexmk
texliveMedium.out                                 1,776 x /nix/store/8g9dvmk0r20mdwminrbrz4wnlwjl9cgz-texlive-2023-env/bin/latexmk
texliveFull.out                                   1,776 x /nix/store/99r9zgqml63mjnnc1pll5mb3x6w3p67g-texlive-2023-env/bin/latexmk
texliveBookPub.out                                1,776 x /nix/store/zwglipcbwx6dshy44f538p7m4rb496jn-texlive-2023-env/bin/latexmk

With a newer tree:

$ nix shell github:NixOS/nixpkgs/fe83bbdde2ccdc2cb9573aa846abe8363f79a97a#nix-index --command nix-locate --top-level /bin/latexmk
error: unexpected argument '--top-level' found

  tip: to pass '--top-level' as a value, use '-- --top-level'

Usage: nix-locate [OPTIONS] <PATTERN>

For more information, try '--help'.
