feat(bun): Expose spotlight option in TypeScript (#18436)

(closes #18419)
(closes
[JS-1261](https://linear.app/getsentry/issue/JS-1261/add-support-for-spotlight-in-sentrybun))

It seems that for Bun we are already using the init function of
`@sentry/node`, so all the options are passed do satisfy the
`NodeOptions`. This is now re-exporting `spotlight` as an option.
