Ready for review @sbillinge. This will fix the current issue of not displaying the latest changelog. Ref Billingegroup/release-scripts#94

Once you've merged this, could you please run this Deploy Documentation on Release workflow via dispatch? We should then see the latest v0.2.0 news under here https://www.diffpy.org/diffpy.fourigui/release.html

@cadenmyers13 cc'ing Caden here. Since Andrew's PR has been merged #67, let's also check whether the API section builds.

Changeling appears in the docs now but still no API documentation building?

Deploy docs workflow ran successfully on dispatch
awesome!

@cadenmyers13 could you please check with Andrew why Api doc isn't rendering ?

https://github.com/Billingegroup/release-scripts/blob/v0/.github/workflows/_publish-docs-on-release.yml

This is the script that @sbillinge used to re-render the doc - displaying the latest changelog 0.2.0 now.
