fix: add sentry.io to network allowlist for OTLP export (#6073)

The AWF firewall was blocking outbound HTTPS to `*.ingest.us.sentry.io`
because it wasn't in the `network.allowed` list. Firewall logs showed 8
requests blocked by `deny-default`.

This adds `*.ingest.us.sentry.io` to the network allowlist so the OTLP
trace exporter can reach Sentry.
