Binaries provided by node packages are not available

Pulling a nixery shell image with nodepackages.mermaid-cli does not contain the mmdc executable. I haven't tested with other node packages, but my guess is that they'd have the same issue.

Actual behaviour: mmdc is not available:

 ~ docker run --rm -it nixery.dev/shell/nodepackages.mermaid-cli
bash-5.1# mmdc --version
bash: mmdc: command not found
bash-5.1# ls -laF /nix/store/*/lib/node_modules/.bin/mmdc
-r-xr-xr-x 1 0 0 310 Jan  1  1970 /nix/store/59c14wz6n6iyk82bmzx8rxzm4sb72xdm-_at_mermaid-js_slash_mermaid-cli-9.1.2/lib/node_modules/.bin/mmdc*
bash-5.1#

Expected behaviour: mmdc should be available, just like in nix shell:

 ~ mmdc --version
zsh: command not found: mmdc
 ~ nix shell nixpkgs#nodePackages.mermaid-cli
 ~ mmdc --version
9.1.2
 ~ ll "${PATH%%:*}"

(I don't think it matters, but I'm running NixOS 22.11.20220604.231efec (Raccoon).
