Non-normalized chatbot responses

**Describe the bug**
Non-normalized responses from chatbot - (not capitalizing the first letter of the sentence, uses whatever was typed in).

**Bug severity**
Minor, non-blocker, purely aesthetic.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to https://nimbus.calpolycsai.com/
2. Submit "What is kurfessss's phone number?" as a question and hit send
3. Wait for a response
4. See non-normalized response (will respond with kurfessss's phone number is xxx)

**Expected behavior**
I expected the output response to be normalized / "correct"

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Additional context**
Should be a pretty easy fix - famous last words from @cameron-toy (but in all actuality, it should be - just need to return the normalized Entity name in the output)
