Change how we check forward-looking upgrade requirements
In https://github.com/snipe/snipe-it/pull/14128 we added the capability for the upgrade.php script to check version requirements _before_ downloading the new source, to help keep from breaking installations. Turns out, `file_get_contents()` isn't a reliable way to grab a url, because some systems have `allow_url_fopen` turned off in their PHP configurations. In this iteration, we swap that out for a curl function, while also adding more error handling, the ability to entirely skip the PHP version checks if for some reason you Just Can't query the upgrade json correctly, as well as adding a lot of helpful text around the whole issue. Additionally, I've added some error checking around DB backups and initial artisan down-ing, since shell_exec would happily march right past any errors.
