docs: add GPU support to HCL

[jpc204]

Summary

• add a GPUs section immediately after the existing DPUs section
• document support for all current NVIDIA data center GPUs
• clarify that platform-specific GPU qualification, certification, thermal, power, and configuration guidance remains with the server manufacturer
• keep the existing host/platform compatibility information at the top of the HCL

Impact

Readers can now confirm NICo's general GPU support policy directly in the Hardware Compatibility List while retaining the existing platform-first organization.

Validation

• git diff --check

Summary by CodeRabbit

• Documentation
  • Added a GPUs section to the HCL documentation.
  • Clarified that NICo supports all current NVIDIA data center GPUs.
  • Stated that GPU compatibility isn’t validated per platform and should be confirmed with the server manufacturer’s guidance.

Walkthrough

The HCL documentation now describes support for current NVIDIA data center GPUs, clarifies that platform-specific compatibility is not validated in the HCL, and directs readers to server manufacturers for qualification details.

Inline comments:
In `@docs/hcl.md`:
- Around line 65-67: Update the “Last Updated” metadata in the HCL documentation
to reflect the addition of the GPUs section, using the current date of the
change. Leave the GPU support content unchanged.
- Around line 67-73: Clarify the GPU table’s “Supported” scope by renaming the
support column or qualifying the row to explicitly describe NICo/NVIDIA
software-stack support, consistent with the page disclaimer. Replace the
unbounded “Current NVIDIA Data Center GPUs” wording with a release/date anchor
or an explicit supported GPU-family list, while preserving operator-facing
guidance.
- Around line 71-73: Update the GPU support table in the HCL documentation so
the header, separator, and data rows all have leading and trailing pipes,
following the repository’s required MD055 table style.
