fix(core): correct return type hints in BaseChatPromptTemplate (#32009)

Browse Source 
This PR changes the return type hints of the `format_prompt` and
`aformat_prompt` methods in `BaseChatPromptTemplate` from `PromptValue`
to `ChatPromptValue`. Since both methods always return a
`ChatPromptValue`.
