* Utilizes the new standard WebAPI Fetch Headers.getSetCookie() function
to safely handle multiple set-cookie headers when converting from a
WebAPI Response to a NodeJS ServerResponse
Modifies the existing nodeMiddleware logic which first set AstroCookies
on ServerResponse.setHeader(...) and then called
ServerResponse.writeHead(status, Response.headers) which means any that
if the WebAPI Response had any set-cookie headers on it, they would
replace anything from AstroCookies.
The new logic delegates appending AstroCookie values onto the WebAPI
Response Headers object, so that a single unified function safely
converts the WebAPI Response Headers into a NodeJS compatible
OutgoingHttpHeaders object utilizing the new standard
Headers.getSetCookie() function provided by the undici WebAPI polyfills.
Plus extensive test coverage.
* #7226 - changeset for NodeJS adapter set-cookie fix
* fixing all double quotes to single quotes
