Being prompted with a v0.10.5 update however its not in the changelog

Description
Hi there,

I was about to update the Cookbook app on my NC to a reported v0.10.5 and went to check the changelog but it doesn't seem that such a version exists in CHANGELOG.md. It also seems that the last version bump in Github Actions was from 0.10.3 to 0.11.0-rc1.

I'm not familiar with the deployment/update workflow for NC apps but thought it worth mentioning. In the best case it's just been a manual push and there's no clear notes. Potentially it's actually updating to v0.10.3 and incorrectly reporting the version number. Worst case the h4x0r5 are coming for our cheesecakes via a malicious Cookbook update!!! 😆

Reproduction
Steps to reproduce the behavior:

1. Install v0.10.2 of Cookbook
2. Go to see available App updates
3. Prompted to update to v0.10.5

Expected behavior
Only known versions of the Application should be presented.
Changelog should have detail on any deployed version.
Presumably the Github Actions (haven't looked) trigger a deployment based on the contents of last_release

Versions
Nextcloud server version: 27.1.3.2
Cookbook version: 0.10.2

Start by comparing CHANGELOG.md with the reported v0.10.5 update and inspect the GitHub Actions version bump from 0.10.3 to 0.11.0-rc1. Check how last_release is used in the deployment workflow and determine whether the advertised version matches a released build and its changelog entry.
