feat(apple): Re-enable watchosArm32 via spm4Kmp 1.9.3

spm4Kmp 1.9.3 adds armv7k (watchosArm32) support to its AppleCompileTarget
enum, so it now generates the exported cocoapods.Sentry cinterop for that
target. Bump Config.spmForKmpVersion to 1.9.3 and re-add watchosArm32() to the
appleTargets list (the swiftPackageConfig forEach iterates that list).

This restores the published target, so validateDistributions (expects
watchosarm32, 20 artifacts) and scripts/build-apple.sh stay consistent.
apiCheck is unaffected (android/jvm dumps only).
