Fix conversational UI setup

Fix conversational UI setup in ChatQnA (Draft)

This PR addresses [https://github.com/opea-project/GenAIExamples/issues/921#issuecomment-2723958947]. It provides a script (use_conversation_ui.sh) to automate switching to the conversational UI, along with a Bash test script (test_conversation_ui_setup.sh).

Important Note: I am currently unable to test these changes due to system limitations (Docker installation issues and low memory). I will be able to test thoroughly in approximately 1-2 months when I have a new system. I am submitting this as a Draft PR to:

• Show the progress I've made.
• Get early feedback from maintainers.
• Allow others to potentially test the changes.
• Avoid the issue getting lost.

Changes Made:

• Created use_conversation_ui.sh to automate the setup process, addressing inconsistencies in the README.
• Created test_conversation_ui_setup.sh (Bash) to verify the changes made by the script.
• Updated the compose.yaml as described in the issue and script.
• Updated the README.md

Testing Status:

• Untested by me due to system limitations.
• Requires yq to be installed to run the test script, sudo apt install yq.

Next Steps (for me):

• Once I have a new system (in 1-2 months), I will:
  • Thoroughly test the changes.
  • Address any feedback from maintainers.
  • Convert this to a regular (non-draft) PR.

Request to Maintainers:

• Please review the code for any obvious errors or improvements.
• If possible, consider testing the changes on your end.
• Let me know if you have any questions or suggestions.

Thank you for your understanding!

Hi @surfiniaburger,
Thank you very much for your help and contribution! We’ve updated the corresponding README and compose files based on the issue, and the inconsistency between the README and the actual service startup process has been resolved.
Regarding conversation-ui, we believe a better approach would be for developers to handle environment variables via Nginx forwarding, rather than reconfiguring them through a shell script.
Thanks again for your support! If you have any further questions or ideas, please feel free to reach out to us anytime.
