Custom text value for `st.chat_input`

type:enhancement feature:st.chat_input

### Checklist - [X] I have searched the [existing issues](https://github.com/st…reamlit/streamlit/issues) for similar feature requests. - [X] I added a descriptive title and summary to this issue. ### Summary I propose to add a parameter to `st.chat_input` that allows for the customization of the user prompt, similar to the `value` parameter of `st.text_input`. ### Why? I have been working on an LLM that is built on top of ChatGPT. On the App page, there's a dropdown of prompt examples that users can choose from, and once they select a prompt, it should automatically appear in the `st.chat_input` box (similar to the prompt examples ChatGPT provides). Unfortunately, there is currently no way to set a custom prompt for `st.chat_input`. As this is a common practice for UIs of chat models, this functionality could be extremely helpful for a lot of applications. ### How? I currently don't have much time to understand the details of `st.chat_input`'s implementation, but I suppose it is at least somewhat similar to how `st.text_input` is implemented. I think the team can look into how the `value` parameter is handled in `st.text_input` and use it as a reference for this functionality. ### Additional Context _No response_
