nodeenv falls back to /usr/bin/nodejs instead of the node installed by actions/setup-node

Description:
In a runs-on: ubuntu-latest GitHub hosted runner, I found that even after doing:

      - name: Set up Node
        uses: actions/setup-node@v4
        with:
          node-version: 16

that pre-commit run -a was failing to run a pre-commit hook configured as:

  - repo: https://github.com/pre-commit/mirrors-prettier
    rev: v3.1.0
    hooks:
      - id: prettier
        args: [--no-editorconfig]
        exclude: "^asv\\.conf\\.json$"
        exclude_types: [html]

with an error saying:

prettier requires at least version 14 of Node, please upgrade

Which was surprising, seeing as how we had just installed node version 16.

It turns out that pre-commit runs nodeenv, and nodeenv looks first for a binary named nodejs, and then falls back to looking for one named node:

https://github.com/ekalinin/nodeenv/blob/eaa9de97e561ab4f99458c94633e92547e72d5f1/nodeenv.py#L931-L938

And it seems like actions/setup-node is only installing one named node, and not one named nodejs, so nodeenv found /usr/bin/nodejs first and preferred that over /opt/hostedtoolcache/node/16.20.2/x64/bin/node.

Should the hostedtoolcache contain a nodejs as well? Or perhaps nodeenv should prefer node over nodejs?

Action version:
actions/setup-node@v4

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:

Repro steps:
See https://github.com/bloomberg/memray/actions/runs/6984525297/job/19007471664 for a failed run where /usr/bin/nodejs was chosen instead of /opt/hostedtoolcache/node/16.20.2/x64/bin/node

Start with the actions/setup-node@v4 workflow and the nodeenv.py lookup around lines 931-938, then reproduce the failing pre-commit run from the linked GitHub Actions job. Trace which executable is selected on Ubuntu hosted runners; the issue is done when the configured Node 16 installation is selected and the Prettier hook succeeds.
