AlloyDB AI pre-registers Gemini 3.x models and semantic-ranker-512 reranking model

AlloyDB AI adds pre-registered support for the following Gemini models in version 1.6.5 and later of the google_ml_integration extension:

• gemini-3.1-flash-lite
• gemini-3.5-flash
• gemini-3.5-flash-lite
• gemini-3.6-flash
• gemini-3.7-flash
• gemini-3.8-flash

Version 1.6.5 of the google_ml_integration extension sets gemini-3.5-flash-lite as the default Gemini model and removes the gemini-2.0-flash, gemini-2.0-flash-lite, gemini-2.5-flash, gemini-2.5-flash-lite, and gemini-2.5-pro models from the list of pre-registered models.

Additionally, AlloyDB AI adds pre-registered support for the semantic-ranker-512 reranking model.
