LOG: [LangRef] Fix examples for float to int saturating intrinsics (#115629)

As per the [LangRef:Simple
Constants](https://llvm.org/docs/LangRef.html#simple-constants), exact
decimal values of floating-point constants are required. For instance,
23.9 is a repeating decimal in binary and results in the reported error.
