Use curly, not straight quotes

**Describe the bug**
Haper should use “curly” or “typographer’s” quotes, not "straight" or "dumb" quotes in suggestions.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to https://writewithharper.com/
2. Click on the second suggestion, Word Choice - “That s”
3. Click the button Replace "That s" with "That's"
4. Harper erroneously uses straight quotes, not curly qutoes

**Expected behavior**
Haper should use “curly” or “typographer’s” quotes, not "straight" or "dumb" quotes.

**Screenshots**

**Platform**
Only tested in Chrome

**Additional context**

Reproduce the replacement flow at https://writewithharper.com/ in Chrome, using the second Word Choice suggestion for “That s”. The payload names no source file or test, so trace that suggestion and its replacement path first; done means the replacement uses curly quotation marks rather than straight quotes.
