Multiline commits not fully supported

**Describe the bug and expected behavior**
As per Git hosting platforms, multiline commits are treated as an essay: the first line is considered as a summary, and the rest of the description separated by a new line is considered as details, and are generaly hidden while displaying the commit log. However, on DoltHub, that is not the case as it seems to display the entire commit as is.

**To Reproduce (please include link if applicable)**
Steps to reproduce the behavior:
1. Using Dolt, create a multiline commit.
```bash
dolt commit -m "This is a
multiline
commit"
```
2. Push changes and open corresponding commit on DoltHub
