feat(VoiceConnection): lower browser runtime error to a warning

The base work around "browser" support was done over 7 years ago.
Although nothing much has changed when it comes to supporting UDP
connections in browsers, over time, browser-like runtimes like Deno,
Bun, and others claiming (partial) Node compatibility (including UDP
connections) have emerged. Although using Dysnomia with these browser-
-like environments won't be officially supported, I think that rather
than blocking them outright, we should acknowledge that those alternative
runtimes exist and allow them to try to use voice at their own risk with
a warning that they might possibly end up seeing undefined or weird
behavior.
