feat: use globally available WebSocket client in runtimes that have it

[vladfrangu]

Please describe the changes this PR makes and why it should be merged:

Bun fixed the WebSocket issue (oven-sh/bun#3392). WS now reports correct close codes and everything! Now, fingers crossed their WebSocket client doesn't have some hidden bugs 🤞

Status and versioning classification:

• Code changes have been tested against the Discord API, or there are no code changes
• I know how to update typings and have done so, or typings don't need updating
