[Docs] order: Remove duplicate mention of default

[johnthagen]

Update docs for import rule / newlines-between option. Default value is taken from:

eslint-plugin-import/src/rules/order.js

Line 588 in ccb69d9

const newlinesBetweenImports = options['newlines-between'] || 'ignore';

[johnthagen]

@ljharb After your feedback, I'm inclined to simply close this PR altogether. Do you concur?

[ljharb]

Maybe not; #2280 (comment)

[johnthagen]

Hmm, it seems like for bullet-list options the default is given inline:

https://github.com/import-js/eslint-plugin-import/blob/main/docs/rules/order.md#alphabetize-order-ascdescignore-caseinsensitive-truefalse

So, I'm back to being unsure about the PR.
