Use global WebSocket constructor if available

[williamhorning]

Which application or package is this feature request for?

ws

Feature

Currently, Discord.js uses the ws module from npm, which works just fine in Node. However, this module causes issues on alternative JS runtimes like Deno.

Ideal solution or implementation

Discord.js should check to see if the WebSocket constructor is available globally and use that instead of the ws module if it's available.

Alternative solutions or implementations

• Discord.js could use isomorphic-ws
• Deno users could wait for fix(ext/node): handle 'upgrade' responses denoland/deno#19412, but that would exclude users of other runtimes

Other context

The error thrown under Deno:

We dont support deno for this moment,
Also it would require more changes

@jaw0r3k This wouldn't just impact Deno users, this would also allow Bun users to use its WebSocket implementation, which they claim is faster than the ws module currently used by Discord.js. I'd be willing to try to do the work needed to make this happen if it isn't that high of a priority for Discord.js at the moment.
