ci(release): pin newer cross NDK image for aarch64-linux-android#86

Conversation
The default image bundled with cross 0.2.5 ships an NDK whose sysroot lacks libunwind on the linker path. Modern rustc emits `-lunwind` for Android targets, so the release build fails with `ld: cannot find -lunwind`. Override just the Android target to a digest-pinned cross main image, which ships an NDK that has libunwind available. All other targets keep their default cross 0.2.5 images.

Summary
aarch64-linux-androidwere failing withld: cannot find -lunwind. Modern rustc emits-lunwindfor Android targets, but the NDK bundled in cross 0.2.5's default Android image doesn't ship libunwind on the linker path (Targetaarch64-linux-androidlink failure: unwind. cross-rs/cross#1222, 0.17.7. briansmith/ring#1853).Cross.tomlthat overrides only the Android target to a digest-pinned cross main image (NDK r25+, libunwind available). All other targets keep their existing cross 0.2.5 images.:maintag, to stay reproducible.Test plan
aarch64-linux-androidmatrix job links cleanly.
