Ruby 3.4 images missing in README

[ybiquitous]

Hello 👋🏼

Today, I happened to notice that Ruby 3.4 images like 3.4.7-jammy are not present in the README.md file, e.g.

docker-images/README.md

Lines 22 to 36 in 7212e3c

Would you happen to know if there is any reason for this missing? If you just forget, I'm glad to open a pull request.

I'd appreciate it if you could take a look. Not an emergency. Thank you.
