Process does not exit after https request with keepAlive enabled (now default in Node 19)

### Version v19.8.1 ### Platform Linux Jake-Framework 6.2.7-arch1-1 #1 SMP PREEMPT_DYNAMIC Sat, 18 Mar 2023 01:06:36 +0000 x86_64 GNU/Linux ### Subsystem https ### What steps will reproduce the bug? Run a script containing: ```js const https = require("https"); const url = "https://github.com/dprint/dprint/releases/download/0.35.3/dprint-x86_64-unknown-linux-gnu.zip"; https.get(url, { method: "HEAD" }, console.log); ``` This will hang. ### How often does it reproduce? Is there a required condition? 100% of the time; downgrade to Node 18 and it no longer hangs. ### What is the expected behavior? Why is that the expected behavior? No hang. Run this: ```js const https = require("https"); const url = "https://github.com/dprint/dprint/releases/download/0.35.3/dprint-x86_64-unknown-linux-gnu.zip"; https.get(url, { method: "HEAD", agent: new https.Agent({ keepAlive: false }) }, console.log); ``` And it will succeed. ### What do you see instead? Hang; the request succeeds and the response is given, but the process never exits. ### Additional information This is a change I saw in the Node 19 release blog post; keep-alive is enabled by default now, but, it seems to cause a hang.
