Enhancement: [prefer-nullish-coalescing] Ignore env vars about typescript-eslint

[bradzacher]

The rule has no concept of platform or framework specific APIs. We purposely do not encode any specifics into any of our rules.

In this instance we would not be encoding special semantics around node's env var API.

It's also not uncommon that you would want the nullish coalescing behaviour instead of the logical or. For example if you want a default value but you want someone to be able to set any other value.

Theres no hard and fast rule that works here.

Which is why there's an option to ignore specific types of primitives based on your preferences.
