[Bug]: Incorrect `li` numbering

[skylee03]

This is actually a issue with Sassline:

• Prevent li of ul from incrementing the counter jakegiltsoff/sassline#60

However, since it is no longer actively maintained, I think we can just fix it in Alembic.

In _typography.scss, counter-increment: none; should be added to unordered list items to prevent them from incrementing the counters.
