## Overview

This change adjusts the release-it config for both this repo, as well as
what the create script generates, so that the previous changes to
enhance the changelog generation flows through to the github release
page too.

I discussed this here release-it/release-it#1025 (comment), and @webpro
theorized it was the autoGenerate that overrode the changelog output
from being applied to the GH release too.

I created a test repo to verify and confirmed that removing
`autoGenerate`, indeed, fixed the issue:
https://github.com/michaelfaith/mf-cta-testing/releases 2.0.2 is after
this change, which included both a chore change and fix change, but
changelog and GH release page only show the bug fix (notice also the
group heading, which isn't in the previous releases). 2.0.1 is before
the change, with the original configuration

Closes #1913
