fix(gooddata-sdk): [AUTO] make CatalogLlmProviderAttributes.models and provider_config nullable

[yenkins-admin]

Make CatalogLlmProviderAttributes.models and provider_config nullable to align with updated OpenAPI spec from GDAI-1350.
Problem ID: P003 | Workflow: https://github.com/gooddata/gdc-nas/actions/runs/23137028021

What changed in gdc-nas

Two commits landed in gdc-nas to fix a 500 error on PATCH LlmProvider operations (GDAI-1350):

• 06ec721 — Made LlmProvider.providerConfig and LlmProvider.models nullable in the Kotlin model (LlmProviderConfig? = null, List<LlmModel>? = null). Added requireNotNull validation in LlmProviderValidator for POST/PUT. Updated EncryptionService and OrganizationApiStockService for null-safe calls. Added patch.json test fixture that patches only the name field.
• abb5c41 — Regenerated OpenAPI spec: removed models and providerConfig from required[] in LlmProvider attributes schema; removed attributes from required[] in JsonApiLlmProviderPatch, JsonApiLlmProviderIn, and JsonApiLlmProviderOut documents; added nullable: true to providerConfig in those three schema locations.

What was implemented in SDK

Updated CatalogLlmProviderAttributes in the SDK wrapper to reflect the updated OpenAPI schema:

• models: list[CatalogLlmProviderModel] → list[CatalogLlmProviderModel] | None = None
• provider_config: CatalogLlmProviderConfig → CatalogLlmProviderConfig | None = None

CatalogLlmProviderPatchAttributes already had both fields optional — no change needed there. CatalogLlmProvider.from_api() already used safeget with fallbacks, so it handles null values from API responses safely.
