build(deps): bump msgpack from 1.1.2 to 1.2.1

[ramakrishnap-nv]

Closes #1451

Summary

• Bumps msgpack 1.1.2 → 1.2.1 across all dependency surfaces: dependencies.yaml (single source of truth), generated conda environments (4 files), conda recipes (cuopt-server, cuopt-sh-client), and generated pyproject.toml files (cuopt_server, cuopt_self_hosted)
• Fixes GHSA-6v7p-g79w-8964: segfault when calling Unpacker.unpack() after an unpacking failure (1.2.1)
• Fixes use-after-free in unpackb()/Unpacker.unpack() for non-contiguous input (1.2.0)

The dependabot PR #1451 only updated cuopt_self_hosted/pyproject.toml directly; this PR instead updates dependencies.yaml and runs rapids-dependency-file-generator so all generated files stay in sync.

In @.pre-commit-config.yaml:
- Around line 10-11: The trailing-whitespace hook exclusion is no longer aligned
with the existing special-case tree handling because the `helmchart` branch was
dropped from the regex while nearby hooks still exclude it. Update the
`trailing-whitespace` entry in `.pre-commit-config.yaml` to keep the `helmchart`
pattern alongside the existing datasets and skills exclusions, and preserve the
new markdown exclusions without removing the `helmchart` branch.
