feat(gooddata-sdk): [AUTO] add CatalogDataSourceAiLakehouse data source type

[yenkins-admin]

Adds CatalogDataSourceAiLakehouse typed subclass to the gooddata-sdk wrapper, reflecting the new AILAKEHOUSE database type introduced in gdc-nas backend.

P006 | Workflow: https://github.com/gooddata/gdc-nas/actions/runs/23235917307

What changed in gdc-nas

• Commit b4e5b11: Adds AILAKEHOUSE as a new database type enum value across OpenAPI specs (metadata-api, sql-executor), proto (dbtype.proto), Kotlin DatabaseType enum, and service layer.
• Key constraint: the backend introduces maybeRedactAiLakehouse() in OrganizationLayout.kt which strips url, token, schema, and parameters from AI Lakehouse data source declarative serialization — only id, name, type, cacheStrategy, and permissions are preserved.
• Feature-flagged behind ENABLE_AILAKEHOUSE_DATA_SOURCE.
• Related Jira tickets: CQ-1987, CQ-1899

What was implemented in SDK

Added CatalogDataSourceAiLakehouse following the CatalogDataSourceGdStorage pattern for data sources that do not expose connection credentials. The class omits url, token, schema, and parameters fields (sets schema='' and uses _NoCredentials) to match the backend's redaction behavior and prevent users from setting credentials that would be silently dropped.

Files modified

• packages/gooddata-sdk/src/gooddata_sdk/catalog/data_source/entity_model/data_source.py — new CatalogDataSourceAiLakehouse class
• packages/gooddata-sdk/src/gooddata_sdk/__init__.py — export CatalogDataSourceAiLakehouse
• packages/gooddata-sdk/tests/catalog/test_catalog_data_source.py — unit tests for construction and serialization

JIRA: PENDING (Jira ticket will be created after review)
Risk: Low
