Fix cspell-lint failure by scoping Azure AI Training vocabulary to extension dictionary

[Copilot]

The cspell-lint Actions job (cspell-ext) failed on the azure.ai.training extension due to unrecognized domain-specific terms in both design docs and Go sources.
This change resolves the failure by adding the missing extension vocabulary to the extension-local cspell config.

• Root cause

  • cspell-ext runs with cli/azd/.vscode/cspell.yaml and cascades into per-extension configs; azure.ai.training/cspell.yaml lacked many terms used by this extension.

• Change made

  • Expanded cli/azd/extensions/azure.ai.training/cspell.yaml words: list with training-specific terminology and identifiers (ML terms, Azure resource naming patterns, API field names, and extension-specific tokens).

• Scope control

  • Kept the fix local to azure.ai.training dictionary instead of broadening global dictionaries, so spelling exceptions remain extension-scoped.

# cli/azd/extensions/azure.ai.training/cspell.yaml
words:
  - serviceinstances
  - safetensors
  - openmpi
  - cudnn
  - sklearn
  - workspaceblobstore
  - experimentids
  - FINETUNING

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
