Do not support ruby 3.2

[Lucas Kanashiro]

ruby-eb/2.6-4build2 FTBFS with ruby 3.2. The upstream project is apparently dead:

https://rubyeb.sourceforge.net/

We have the same upstream release since Trusty! I do not foresee any fix from upstream. To also avoid having unmaintained code in the archive I believe the best way out of this is removing it from Noble, allowing the ruby 3.2 transition to move on.

Since this is a leaf package, the removal is straightforward:

$ reverse-depends src:ruby-eb
No reverse dependencies found
$ reverse-depends src:ruby-eb -a source
No reverse dependencies found

So please, remove src:ruby-eb and its binary from Noble.

I checked this case confirming all you stated in the removal request.
LGTM

Furthermore the use-case of this explains why it might have been abandoned.
It is a less common (except in Japan) cd-rom book type.
And cd-roms have gotten way more rare these days right :-)
This does not remove all ability to access those.

There are eblook and a few go bindings left. But TBH, those just as much depend on an never changed library from src:eb. So there might be more cleanup needed down the road, yet OTOH no need to take things away if not being a problem.
But here blocking ruby 3.2 I think it is justifiable.

Removing packages from noble:
 ruby-eb 2.6-4build2 in noble
  ruby-eb 2.6-4build2 in noble amd64
  ruby-eb 2.6-4build2 in noble arm64
  ruby-eb 2.6-4build2 in noble armhf
  ruby-eb 2.6-4build2 in noble ppc64el
  ruby-eb 2.6-4build2 in noble riscv64
  ruby-eb 2.6-4build2 in noble s390x
