[office-addin-dev-settings] Update commander dependency

[TheSamsterZA]

Expected behavior

Using exported methods from office-addin-dev-settings should not cause compilation to fail.

Current behavior

My app fails to compile.

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

Code snippet:

// app.ts
import { sideloadAddIn } from 'office-addin-dev-settings';

async function foo(path) {
  await sideloadAddIn(path, undefined, true);
}

tsc app.ts

This will fail to compile due to commander. The bug was reported in multiple issues on the repo, and a PR was merged in and released in the 5.0.0.

Context

I am building a CLI that wraps the great functionality provided by the packages that live here in this repo. Unfortunately, due to office-addin-dev-settings using an old version of the commander package, my NodeJS app fails to compile.

• Operating System: Windows 10 Version 20H2
• Node version: 15.1.0 with npm 6.14.8
• Office version: Microsoft Office 2016 Version 2012 (Build 13510.20004 Click-to-Run), Beta Channel
• Tool version: office-addin-dev-settings@1.8.8
