fix(nextjs|sveltekit/v7): Ensure we can pass browserTracingIntegration (#11765)

Turns out the logic to get the options was not correct, because we used
the `options` that the integration exposes, but this has
`instrumentPageload: false` & `instrumentNavigation: false` because we
did not "fix" the `options` we expose on the integration. This was not
caught by the tests, because it only happens if passing the
`browserTracingIntegration` from `@sentry/nextjs` or
`@sentry/sveltekit`, not when passing the "original" one (which we had
tests for).

Really fixes #11627
