Replace old screenshot with new one in HowToGuide for First Pull

Description

Doc to change: https://github.com/swiftlang/swift/blob/main/docs/HowToGuides/FirstPullRequest.md

The screenshot in this doc is showing apple/swift and it's now swiftlang/swift under submitting a pull request. Good first issue for someone!

Hi @parispittman , I would like to start contributing and work on this as my first issue, could you please assign this to me?
The current screenshot has a push ready to be pulled( which I assume has to be there considering its in the section for pull requests) but this feels like a paradox considering I can only send in my first pull request AFTER taking the screenshot. Should I just push a dummy change to take the screenshot? I would appreciate any tips on how to move forward!

Yeah, you just need to push a dummy branch to your fork for that button to show up.
