feat(discord): Improve release announcement formatting

This commit introduces a new function, `formatLauncherVersion`, to parse the release title and format it more clearly for Discord announcements.

The new format extracts the app name, version, and build number, transforming a title like `- AppName ‧ (1.11.2.6)` into `AppName 1.11.2 Build 6`.

Additionally, the calculation for the `Content-Length` header in the webhook request has been corrected to use `Buffer.byteLength(payload)` instead of `payload.length` to ensure accurate byte counting for the JSON payload.
