This patch fixes GCC Bug 108760:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108760

Before this patch, using std::ranges::iota required including <algorithm> when it should have been sufficient to only include <numeric>.

When the patch is applied, the following code will compile:  https://godbolt.org/z/33EPeqd1b

I added a test case for this change as well.

I built my local version of gcc using the following configuration:  $ ../gcc/configure --disable-bootstrap --prefix="$(pwd)/_pfx/" --enable-languages=c,c++,lto

and I tested my changes by running:  $ make check-c++ -jN -k

I ran this on the following OS:

Virtualization: wsl
Operating System: Ubuntu 20.04.6 LTS
Kernel: Linux 5.15.146.1-microsoft-standard-WSL2
Architecture: x86-64
