The example for building busted fails - nlua not found

See https://github.com/ColinKennedy/nvim-best-practices-plugin-template/actions/runs/10969773023

This is reproducible with the "Full Example" in this repo's README

name: test

on: [push]

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@master

    - uses: leafo/gh-actions-lua@v10
      with:
        luaVersion: "5.1.5"

    - uses: leafo/gh-actions-luarocks@v4

    - name: build
      run: |
        luarocks install busted
        luarocks make

    - name: test
      run: |
        busted -o utfTerminal

It could be an issue with busted or with this GItHub action. Some clarity would be appreciated.
