Feature: More effective ways to add items to Evaluation Dataset.

[634750802]

Directly add an answer to an Evaluation Dataset

An answer could be added to evaluation dataset when:

• The message was already finished
• The message was NOT replying appended questions (the first answer to the question)

Answer page should add a new add to evaluation dataset interaction button for admin user.

There are two options to implement this feature:

• Construct evaluation dataset item data from frontend and calling the create evaluation dataset api
• Server provide a new api create evaluation dataset from chat message

Automatically add liked answer to configured Evaluation Dataset

Not sure how to deduplicate answers in current implementation
