Comment (by Roland Haas):

Thank you for reporting these and providing fixes.

It turns out that these steps are already on the ET release process page (two items actually):
* https://docs.einsteintoolkit.org/et-docs/Release_Process#create_branches
* and earlier:

Update einsteintoolkit.bib (https://bitbucket.org/einsteintoolkit/manifest/src/master/) with

Requested and suggested citations for all thorns in thorn list (10 minutes).
Latest release info and DOI (from Zenodo entry above)

so the issue is that steps were skipped (or “thorns” was taken to really mean only “thorns” and not “ET components”).
