Respect package.json field packageManager if present - Option to use Corepack maybe?

[o-l-a-v]

Is your feature request related to a problem? Please describe.

NodeJS and Yarn ( https://yarnpkg.com/corepack ) wants package managers to be treated as any other package with the packageManager field in package.json + Corepack. pnpm also supports this ( https://pnpm.io/installation#using-corepack ). And NPM in NodeJS obviously.

Describe the solution you'd like

Would be great if the GitHub action either respected the packageManager field in package.json, and/or if we had the option to use Corepack instead.

Describe alternatives you've considered

None at this point.
