litellm: update to 1.89.2

[dylanmtaylor]

Description

Updates the LiteLLM hardened image from 1.84.0 to 1.89.2, the latest upstream stable release from BerriAI/litellm. This brings DHI in line with the current upstream release as requested in #437.

Type of Change

• Bug fix (image is out of date)

Related Issues

Fixes #437

Changes Made

Updated both image/litellm/debian-13/1.yaml (runtime) and image/litellm/debian-13/1-dev.yaml (dev):

• Version vars _VERSION / VERSION / SEMVER_VERSION / DEBIAN_EPOCH_VERSION: 1.84.0 → 1.89.2
• SEMVER_MAJOR_MINOR_VERSION / DEBIAN_EPOCH_MAJOR_MINOR_VERSION: 1.84 → 1.89
• _COMMIT_SHA / COMMIT_SHA, source url and checksum: e1fc955… → 94dae27… (upstream tag v1.89.2)
• Image tags and SPDX version / purl (pkg:pypi/litellm@1.89.2) updated accordingly

The Python base image references (3.13.14), CVE remediations, and npm patches are intentionally left unchanged — this matches the scope of prior LiteLLM version-bump commits.

Testing

• Both YAML files parse correctly
• Verified commit SHA 94dae27b0c555d2549ee5077a16d6ea5542244bd matches upstream tag v1.89.2
• Confirmed all version/SHA references were updated consistently with no stale 1.84 references remaining

Note: I was unable to run a full DHI image build locally, as it depends on the dhi.io/build toolchain. CI build verification would be appreciated.
