fix: Re-export _INTERNAL_normalizeCollectionInterval in dependent packages

The consistent exports CI check requires that packages depending on
@sentry/node re-export everything @sentry/node exports. Add the missing
_INTERNAL_normalizeCollectionInterval re-export to @sentry/astro,
@sentry/bun, @sentry/aws-serverless, and @sentry/google-cloud-serverless.
