Fig bug in vertical size of ROR logo

[cthoyt]

Motivated by openjournals/joss#1353 (comment)

This removes a vestigial part of the logo that doesn't actually do anything, and in result, gets rid of the weirdly tall characteristic of the ROR logo that caused an issue for longer author lists

In a silly test, I made one of the affiliations very long to show that the spacing is fixed:

This PR also makes a few minor changes:

1. Fixes the example-doc.yml workflow to build from the current repository, rather than using what's on DockerHub, which is always wrong if you are updating the templates
2. Fixes a minor typo and formatting issue in the CHANGELOG

Hi @tarleb, this fix addresses an issue happening in production for JOSS noticed by @arfon, would you please take a look at this minor bugfix then make a new Inara release? Thanks!

Looks good, thank you! Could squash the logo fixes into a single commit? I'd do a squash merge, but then we'd squash the CI fixes as well, which I'd like to avoid.

@tarleb done - I just rewrote the commit history accordingly
