Gemini Embeddings 问题：Discourse 更新到 3.6.0 Beta 2 后

[Falco]

Duplicate of Gemini embedding setting not passing output_dimensionality?

@RBoy

@Falco maybe the default gemini configuration needs to be updated in discourse, when creating a new gemini embedding it still uses embedding-001 instead of gemini-embedding-001

FEATURE: Support for newer Gemini Embedding model
