Upgrade proxy-extend to use modern Node.js 14+ features.

- Convert package to ES modules by default using `module: "type"`.
- Use `exports` in `package.json` rather than `main`. This is technically a breaking change due to the change
  in which subpaths can be imported.
- Drop support for Node 12.
- Upgrade to package-lock v2 format.
