Use @actions/tool-cache to manage pnpm versions instead of forcing download

[GregoireW]

Github action did have a process to manage tooling: https://github.com/actions/toolkit/tree/main/packages/tool-cache you can find a tool version before download and install. On self hosted runner, if you already have the tool in the cache, it means it is wwwaaayyyyy faster to setup.

Is there plan to support this ?

thank you
