[libcxx-commits] [libcxx] [libc++][docs] Confirm that P2372R3 has been implemented (PR #148573)

[A. Jiang via libcxx-commits]

https://github.com/frederick-vs-ja created https://github.com/llvm/llvm-project/pull/148573

In #125921, the changes requested by P2372R3 were completed and tested together with corresponding `chrono` types. But that PR didn't mention P2372R3. The `__cpp_lib_format` FTM was even bumped by an earlier PR #98275.

This PR confirms that P2372R3 was completed in LLVM 21 (together with P1361R2). Closes #100043.
