feat: expose statusText in request() ResponseData

[domenic]

Fixes: #4783

This relates to...

#4783

Rationale

Although status text is already captured by the HTTP parser and passed through the request chain via onHeaders(statusCode, rawHeaders, resume, statusMessage), it was being dropped and not exposed in the ResponseData returned by request(). This makes it difficult for libraries like jsdom that need access to the status text for web platform API compatibility.

Although status text is kind of a useless feature, and so I understand the desire to omit it, the cost of passing this along is minor, and most consumers can ignore it, so I wanted to propose that we keep passing it.

Changes

Expose statusMessage (received from the parser) as statusText in the ResponseData object returned by request().

Features

• Added statusText property to ResponseData returned by request()

Point for discussion

statusText or statusMessage? Undici uses both internally. Fetch uses statusText. Node.js uses statusMessage. I'm fine either way.
