Migrate to upstream Simple-Web-Server submodule

[cgutman]

Description

This PR changes the Simple-Web-Server submodule to the upstream actively maintained version. It turns out that all functionality that was specific to our fork was either implemented upstream or could be achieved without modifying the Simple-Web-Server code itself (by creating a class derived from SimpleWeb::Server<HTTPS>).

Looks like Simple-Web-Server doesn't currently build with the version of Asio included in Boost 1.71. I have submitted a MR to fix it: https://gitlab.com/eidheim/Simple-Web-Server/-/merge_requests/268

Once that is merged (or another fix is committed), I'll update the submodule again and that should fix the build break on those couple broken jobs.
