What happened:

Noticed:

• https://googleforgames.github.io/quilkin/v0.6.0/book/installation.html
• https://googleforgames.github.io/quilkin/v0.5.0/book/using.html

Has the image as us-docker.pkg.dev/quilkin/release/quilkin:0.6.0-92b4920 (or similar for past releases)

What you expected to happen:

Should be: us-docker.pkg.dev/quilkin/release/quilkin:0.6.0

How to reproduce it (as minimally and precisely as possible):

Look at the docs
