fix(ci): drop watchOS from release cross-compile — ring 0.17.14 bug (v0.5.888)

v0.5.887's macOS aarch64 build failed because the workflow
cross-compiles to `arm64_32-apple-watchos` (32-bit ARM pointers
with 64-bit regs). ring 0.17.14 has a const-eval assertion
(`size_of::<usize>() == _ASSUMED_POINTER_SIZE`) that fails for
arm64_32, plus aes_gcm/aarch64.rs calls a method that doesn't
exist on its own gcm::Context.

Drop watchOS from both the cross-compile build loop and the
staging-copy loop. tvOS + visionOS unaffected (aarch64 only).
watchOS users who want native binaries are on a tier-3 follow-up
path anyway. Re-add when ring publishes a fix.
