Apply packageManager minimum for package manager directives

Currently there's a .npmrc and pnpm-workspace.yaml created in the template/ directory but they rely on directives which may not be available for the pnpm version install

as such we should update the package.json to declare per the package manager selected by the user as follows for when it is pnpm as an example:

  "devEngines": {
    "packageManager": { "name": "pnpm", "version": ">=11.0.0", "onFail": "download" }
  }

but the devEngines is only needed for when the package manager is pnpm. When it is npm, you just need to set the engines field (with the npm version being >= 11.10.0)

Also the template package.json file has the wrong version set for the pnpm, it's currently set to this in the sao.js file which has the logic to set it:

'use strict'
const validateNpmPackageName = require('validate-npm-package-name')

const PACKAGE_MANAGER_ENGINES = {
  pnpm: '>=10.26.0',
  npm: '>=11.10.0'
}

so this also needs to be fixed
