Pre-load dotenv to properly load db env variables

[benpbolton]

Minor update to README for UX.

Description

Adding a NODE_OPTIONS preface to the command to pre-load dotenv

Motivation and Context

When a user specifies custom database parameters in .env, these are not currently loaded during an npm run db:migrate. Pre-loading dotenv through the NODE_OPTIONS is a low-lift one-line option to assist someone walking step-by-step through the instructions.

How Has This Been Tested?

Personal experience:)

Happy to close this if it's undesirable to leverage the existing dotenv stuffs, even the npm run start standalone instruction could potentially benefit from this.
