fix: [#1546] Use globalThis instead of global to make Happy DOM work in other runtimes such as Cloudflare workers (#1546)

`global` is a legacy, node.js-only global variable. 

I think `globalThis` this should be used instead, which will make global-registrator portable on other runtimes like Cloudflare workers.
