Subject: [PATCH 2/4] [docs][clang-tidy] Correct StrictMode example in
 modernize-use-std-print

Updated the example in the StrictMode section of the clang-tidy check modernize-use-std-print.

The previous example incorrectly swapped the cast of signed and unsigned integers. Specifically:

The signed integer i was being cast to unsigned int, and
The unsigned integer u was being cast to int.
This correction ensures that the behavior of std::print with StrictMode enabled matches that of printf, by reversing the casts to maintain the correct signedness.

Issue Refference
It solves #llvm#101397
