Fixed building on MacOS Monterey 12.3

refs https://github.com/nodejs/node-gyp/blob/f5fa6b86fd2847ca8c1996102f43d44f98780c4a/lib/find-python.js
refs #1552

- Monterey 12.3 removed Python 2, so `node-sqlite3` doesn't build because
  the v3 binary is called `python3` and therefore `python` is missing
- `node-gyp` has logic to find the python binary and stores it in the `PYTHON`
  env variable
- we should be able to switch to using that
