chore(deps): Bump @sentry/nextjs and @sentry/browser to 10.65.0

Fixes docs traffic classification. The tracesSampler reads
samplingContext.normalizedRequest to classify traffic (AI agent / bot / user)
and sample accordingly, but @sentry/core did not populate normalizedRequest in
the sampling context for root spans until 10.63.0
(getsentry/sentry-javascript#21833). On the previous 10.55.0 that field was
always undefined, so all traffic was classified "unknown": agent traces
under-sampled, bots not filtered, and docs.trace.sampled unable to segment.

No code changes needed — the existing sampler works once the SDK populates the
field. Also consolidates the previously split @sentry/core versions onto 10.65.
