Upgrading `@sentry/nextjs` increases build time

Sentry Feedback: [JAVASCRIPT-31SZ](https://sentry.sentry.io/feedback/?feedbackSlug=javascript%3A6696624399&project=11276&referrer=Linear)

We just upgraded @sentry/nextjs from 7.106.0 to 9.30.0 and it increased our build time from 4 to 7 minutes. Is this expected and is there anything we can do to mitigate?
