Bump github.com/IBM/vpc-go-sdk from v0.68.0 to v0.68.1 (#2648)

SDK Compatibility Patch - Protocol Handling
The SDK was patched to handle additional protocol values introduced in
newer API versions, ensuring older SDK releases do not fail when reading
security group or network ACL rules created with expanded protocol support.
