Fixes the case that the instrumentation defaulted to GET in case undefined was parsed as a second fetch argument.
const request = new Request("https://httpbin.org/post", { method: "POST" });
const response = await fetch(request, undefined); <-- will be GET (should be POST) 
Note
The pull request "fix(core): Parse method from Request object in fetch" was created by @s1gr1d but did not reference an issue. Therefore this issue was created for better visibility in external tools like Linear.
