[BOT ISSUE] Azure: add azure provider to gpt-oss-120b, add standalone gpt-oss-20b entry

[github-actions]

Azure missing from gpt-oss-120b providers; gpt-oss-20b missing as standalone entry

1. gpt-oss-120b — missing azure provider

The catalog entry at line 5806 has available_providers: ["cerebras", "openrouter"] but Azure lists gpt-oss-120b as an available model (Preview, requires Foundry project).

• Azure status: Preview, 131K context, 131K max output, text-only, reasoning
• Catalog providers: cerebras, openrouter (missing: azure)

2. gpt-oss-20b — no standalone entry

Only accounts/fireworks/models/gpt-oss-20b exists (Fireworks-specific). Azure lists gpt-oss-20b as a Preview model available via managed compute and Foundry Local. A standalone gpt-oss-20b entry should exist with azure as a provider.

• Azure status: Preview, 131K context, 131K max output, text-only, reasoning

Sources

• Azure OpenAI Models — gpt-oss section — both models listed with specs
• Azure Model Retirement Schedule — no retirement date set for either

Autofix skipped because the issue body/title did not contain parseable bot metadata for a model catalog change.
