Remove moment.js

[maggie44]

Moment.js is largely deprecated. It's own README included in the installed package states:

## Project Status

Moment.js is a legacy project, now in maintenance mode.  In most cases, you should choose a different library.

For more details and recommendations, please see [Project Status](https://momentjs.com/docs/#/-project-status/) in the docs.

It looks like in the SDK it is only used here: https://github.com/balena-io/balena-sdk/blob/master/lib/util/date.ts

It would be nice to switch to something else, because the Balena SDK is already the largest node_module in my projects, followed only by moment:

When size matters, catching these low hanging fruit makes a difference.

yarn why moment
└─ balena-sdk@npm:16.19.7
   └─ moment@npm:2.29.2 (via npm:^2.29.1)

Thanks for raising this. I will pass this internally and prioritize accordingly.
