Bump rb_sys for ruby 4.0 cross-compile support - #13

0.2.3 (serverscom#12) added source-level ruby 4.0 support, but the precompiled gems it published only ship a 3.4 binary (verified by downloading the actual x86_64-linux gem and checking its spec). Root cause: Gemfile.lock had rb_sys locked at 0.9.105, way older than even the 0.9.124 already pinned in Cargo.toml, and unrelated to the rake-compiler-dock-image:1.12.0 tag the docker/Dockerfile.* files already reference. The cross-gem release job reads the rb_sys version straight out of Gemfile.lock to decide which rake-compiler-dock image to use, so it silently built against an image that predates ruby 4.0 (and 3.3) support and dropped both from the fat gem instead of failing loudly. Bumping rb_sys to 0.9.128 (latest, pulls in rake-compiler-dock 1.12.0, matching the Dockerfiles) and rb-sys to the same version in Cargo.toml for consistency. Recompiled and ran the full spec suite locally against ruby 4.0.6 - all green.
