Function Description

Title:
Add support for Solar-Pro and Solar-Pro2 models, and fix Embedding model input error in Dify Upstage plugin

Description:
We would like to request the following updates to the Dify Upstage plugin:

Model Support
- Please add support for the following Upstage models:
  - solar-pro
  - solar-pro2
Embedding Model Error
- The embedding model solar-embedding-1-large-query , solar-embedding-1-large-passage is currently not working correctly.
- When calling the API, we encounter the following error:
```
[models] Bad Request Error, Error code: 400 - {'error': {'message': "'$.input' is invalid. Please check the API reference: https://developers.upstage.ai/docs/apis/embeddings", 'type': 'invalid_request_error', 'param': 'input', 'code': None}}
```
- This seems to indicate that the request payload does not match the expected API format. Please update the plugin to send the correct input parameter according to the [Upstage Embeddings API reference](https://developers.upstage.ai/docs/apis/embeddings).

Expected Outcome:

The Dify Upstage plugin should support solar-pro and solar-pro2.
The embedding model solar-embedding-1-large-query should function without request errors.
