Breaking/Deprecated API Changes
- Refactor prompt template (7319)
- Use `BasePromptTemplate` for generic typing
- Use `PromptTemplate`, `ChatPromptTemplate`, `SelectorPromptTemplate` as core implementations
- Use `LangchainPromptTemplate` for compatibility with Langchain prompt templates
- Fully replace specific prompt classes (e.g. `SummaryPrompt`) with generic `BasePromptTemplate` for typing in codebase.
- Keep `Prompt` as an alias for `PromptTemplate` for backwards compatibility.
- BREAKING CHANGE: remove support for `Prompt.from_langchain_prompt`, please use `template=LangchainPromptTemplate(lc_template)` instead.
