Feature request: Support alternative package managers

### Describe your idea/feature/enhancement

Right now SAM install dependencies through NPM. If the project makes use of alternative package managers (`pnpm` or `yarn`) this may cause issues since lock files may not be respected, leading to unpredictable builds. It would be nice to support alternative package managers as well.

### Proposal
