Rollup merge of #156354 - lms0806:issue_156102, r=chenyukang

Update example code of `std::array::from_fn`

Since the std::array::from_fn feature has been stabilized since version 1.91.1, the comment stating that it is not stable has been removed.

Additionally, the related example code has been modified into a simple example that is easy to understand.
