http.request should be documented to receive an headers array

Description of the problem

It appears that the implementation of http.request allows sending headers as an array of strings, similar to response.writeHead. However, this feature is not documented. I am wondering if this is an oversight or intentionally left undocumented. If it is not intentional, I would be happy to update the documentation to reflect this functionality. I just wanted to confirm before proceeding.

From my shallow analysis of

node/lib/_http_client.js

Line 294 in 4a4aa58

const headersArray = ArrayIsArray(options.headers);

it seems that Array here is not something coincidentally working but rather explicitly handled as one of the possible value on options.headers so I thing it should be also mentioned in documentation, but of course I may be wrong 😅

Edit: on the other side I found some old issue #2400 - this is about Array in Array ([['Content-Type', 'text/plain'], ['X-Data', 'hello world']] in options.headers but maybe it also has relevance in context of this issue.
