chore(skills): refresh stale Relay signatures

[exactlyallan]

Overview

Refresh two stale NeMo Relay skill signatures that are currently blocking publication through the NVIDIA skills catalog sync.

• I confirm this contribution is my own work, or I have the right to submit it under this project's license.
• I searched existing issues and open pull requests, and this does not duplicate existing work.

Details

• Remove the stale skill.oms.sig bundle from nemo-relay-get-started.
• Remove the stale skill.oms.sig bundle from nemo-relay-plugin-observability.
• Reflow existing Markdown in each affected SKILL.md without changing rendered
  instructions, ensuring NVCARPS includes both skills in its signing input set.
• Leave all references, evaluations, cards, and benchmarks unchanged.
• Trigger /nvskills-ci so the signing bot regenerates content-aligned bundles and validation artifacts.

Do not merge until the Attach NVSkills validation signatures bot commit lands and both affected skills pass content-integrity verification.

Where should the reviewer start?

Start with the two deleted signature bundles and the rendered-content-neutral Markdown reflows. NVSkills CI should restore each bundle with digests matching the current skill content.

Validation before opening:

• Reproduced the catalog integrity failure against current NVIDIA/NeMo-Relay/main.
• Confirmed exactly one mismatched signed file in nemo-relay-get-started.
• Confirmed exactly five mismatched signed files in nemo-relay-plugin-observability.
• Confirmed the only non-generated changes are rendered-content-neutral Markdown reflows in the two affected SKILL.md files.
• git diff --check

Summary by CodeRabbit

• Chores
  • Removed obsolete signature metadata from the Nemo Relay getting-started and observability skill packages.
• Documentation
  • Updated Markdown formatting in the getting-started and observability skills’ guides (line wrapping only) to improve readability, without changing meaning or instructions.
