Add support for spotlight in @sentry/bun

[Asynchronite]

Problem Statement

Currently, most JS SDKs have the ability to enable Sentry Spotlight by just togglint spotlight to true. However, @sentry/bun does not support this, and since bun is currently on a steep climbing pace to be one of the best package managers AND runtimes, this sounds like a no-brainer.

Solution Brainstorm

Not that familiar with Sentry to brainstorm something low-level like this 😅
