vendor: bump cilium to v1.13.1

Although Hubble CLI is unaffected here, bumping Cilium to v1.13.1 should
help stop some security scanner from complaining about the following
3 vulnerabilities that affect Cilium v1.13.0:

Potential network policy bypass when routing IPv6 traffic:
GHSA-8fg8-jh2h-f2hc

Cilium eBPF filters may be temporarily removed during agent restart:
GHSA-r5x6-w42p-jhpp.

cilium-agent container can access the host via `hostPath` mount:
GHSA-4hc4-pgfx-3mrx
