Improvements to tag/release process

[djjudas21]

Describe the bug

I maintain a helm chart for this project over at https://github.com/djjudas21/charts/tree/main/charts/hammond.

I noticed that the README for this project announces a new version of the application in 05bb22f but that there is no corresponding tag for 2022.04.26.

I also noticed that the Docker image that was built for version 2022.04.26 is present on Docker Hub tagged as version 1.0.0.

It's quite hard to track and deploy the correct versions of this project without proper use of tags.

Expected behavior
If it is possible, I would like to see:

1. Development taking place in branches, and merged to main when it is ready
2. Tags/Releases made on the git repo to coincide with the same versions you list in the README
3. Docker images available on Docker Hub tagged with the same versions as the tags on this repo

If you want any help with this, I'm a devops engineer so this is my bread and butter 😃 I can either assist as a maintainer, or show you how to do it. I'm also experienced with automation via Github Actions which can do a lot of this stuff for you, automatically. But I think consistent tagging will bring huge benefits for admins and users of this app. Thanks.
