RFR: JDK-8297000 [jib] Add more friendly warning for proxy issues [v2]

Wed Nov 23 12:10:23 UTC 2022

> When jib tries to download itself behind a proxy, sometimes it can get a different file than it expected. This can result in cryptic errors that are hard to troubleshoot. Let's handle this a little more gracefully by detecting it in the bootstrapper and printing an error.
