The heroku/buildpacks:20 and heroku/builder-classic:22 builder images were:

It's now time to stop updating these images.

This will help offset the growth in our CI/publishing matrix after the recent addition of heroku/builder:24 (which added many more jobs, given it's also multi-arch).

Before we stop publishing the images, we'll want to update the EOL messaging in them one last time, to make the message about "stopping receiving updates in the future" be current/past tense instead.

GUS-W-15677907.

Updates the EOL message to reflect that we're now stopping
updating these images. I've also removed the explicit builder
image name example from the message, since it will get out
of date once future builders are released.

The messaging has to be updated in this separate PR first, so we
can do one more release with the new messaging before
removing the publishing jobs in the next PR.

Towards #512.

This is the cnb-shim equivalent of:
heroku/cnb-builder-images#513

Towards:
heroku/cnb-builder-images#512.

…lassic:22` (#514)

Since these images were:
- superseded by the `heroku/builder:*` images in June 2022
- officially deprecated in Oct 2023 (#429)
- made to error by default in March 2024 (#474)

Builds can still continue using the last version of these builders
published to Docker Hub, and the resultant app images can
still be rebased onto newer run images if needed.

I've also cleaned up the available images table in the README,
to make it display a little better. (There was too much content
before, causing the table to wrap awkwardly when viewed in
the narrow GitHub repo-root view.)

Closes #512.
