Release-prep PR for v2.9.3 (security patch release off release-v2.9), per RELEASES.MD.

What's in v2.9.3

Security and dependency fixes backported to release-v2.9 since v2.9.2:

🔒 Security

🛑 Breaking

  • Dropped support for the OpenCensus receiver (#7323)

🧰 Bug fixes

  • metrics-generator: fix panic when write_relabel_configs is configured (#7338)

🔧 Changes

  • Updated Prometheus to v0.311.3 and OTel Collector deps to v1.52 (#7338)

Changes in this PR

  • CHANGELOG.md: add the # v2.9.3 section. Prometheus, OpenCensus, the metrics-generator panic fix, and the busybox removal already had .chloggen/ entries; this PR adds the missing security entries for the Go 1.26.3, x/net, x/crypto, x/sys, and thrift bumps, then collates everything via make chlog-update VERSION=v2.9.3.
  • Image tag bump to 2.9.3: make bump-tempo-image-tag TEMPO_IMAGE_TAG=2.9.3 + make jsonnet, updating example configs, docs, and compiled jsonnet. Done before tagging per the release process.

Rebased onto the latest release-v2.9 (now including the Go 1.26.3 upgrade #7421).

Once merged, the v2.9.3 tag will be cut on the merge commit to trigger the release/docker workflows.

Add the v2.9.3 changelog section and bump the tempo image tag to 2.9.3
in example configs and compiled jsonnet. v2.9.3 collects the security
dependency updates (golang.org/x/net, golang.org/x/crypto,
golang.org/x/sys, github.com/apache/thrift), the busybox removal
(CVE-2025-60876), the Prometheus/OTel dependency bump, a
metrics-generator panic fix, and the OpenCensus receiver removal
backported to release-v2.9.
