Updates ruby-compiler-dock to 1.4.0 which brings Ruby 3.3 final support
per
https://github.com/rake-compiler/rake-compiler-dock/releases/tag/1.4.0
and starts cross-compiling for ruby 3.3.
I can't find obviously where the test infrastructure configuration is to
run the tests under Ruby 3.3, so might need pointers or an accompanying
PR for the test infra. (I note #31991 from @apolcyn so perhaps currently
they are not run against newer versions)
Fixes#35396
- Backport to `1.60` is desirable since currently the Ruby gems cannot
be installed with Ruby 3.3 and have to be built from source.
Closes#35399
