feat: Support volta, asdf, and package.json engines for declaring version

[happycollision]

⚠️ I only ran the build script. Not sure if there is anything else needed.

This addresses #109 and #84 and could be extended later to also address #150.

Using the same logic as actions/setup-node, we can support asdf, volta or other version management techniques.

I thought it'd be nice to allow something like this:

on:
  - push
  - pull_request

jobs:
  install:
    runs-on: ubuntu-latest

    steps:
      - uses: pnpm/action-setup@v4
        with:
          version_file_path: ".tool-versions" # with asdf
          # version_file_path: "package.json" # with volta or package.json's `engines`
