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

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

NodeJS and Yarn ( ) wants package managers to be treated as any other package with the `packageManager` field in `package.json` + Corepack. pnpm also supports this ( ). 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.
