Ah, I think the darwin issue is because the darwin linker hack was not being applied, I needed to change |

changed the title
- Add Ruby 4.0 - Drop Ruby 3.1 - alpine: Bump to 3.23 and add yaml-dev - Bump host ruby to 3.4 - Rubocop target version 3.2, and associated style changes
- Drop Ruby 3.1 (required ruby version is now `>=3.2`)
- Bump some dev dependencies along the way
- Bump macos runners to macos-15{-intel}
- Re-enable sanitize test
- Make sure the darwin linker hack applies in Ruby 4
because JRuby 9.4 =~ Ruby 3.1 for which we're dropping support. Bump rake-compiler-dock to v1.11.1.
Note we have to jump through some new hoops to use bundler in test-gem-install because ruby's bundled minitest is still v5 and we want to be explicit about using v6. Also note, we need to install build-essentials into the JRuby containers to compile prism, which is a dependency of MT6.
It's not clear to me why this is failing, but it seems like the ZLIB_ENABLED flag is set at compile time and then the library refuses to decompress. Not sure if it's an msys issue or what, but I don't have time right now to investigate.
