`format_to` chrono compilation failure with msvc 14.32 and 14.33(_MSC_VER=1932 and 1933) in C++20

This issue only appears when using msvc 14.32 and 14.33(_MSC_VER=1932 and 1933) in C++20 and I was not able to set that up in godbolt because only the last vcpkg version is visible. Here is the issue:
https://godbolt.org/z/f5b9hnPv4

Notes:

• changing to msvc 14.34 or latest will not hit that issue (so workaround: use latest msvc);
• this looks like a conflict somewhere related to how the standard library is implemented in that case;
• I can reproduce the issue using clang 15.0.1 locally in which cases it uses the msvc version I have installed, which goes with last point; unfortunately I cannot reproduce this setup using compiler explorer;
• initially found when packaging for build2 : Release 9.0.0 and 9.1.0 build2-packaging/fmt#4 ;
• affects at least 9.0.0 and 9.1.0

Looks like the problem is that std::format_to is picked by ADL. The fix is to namespace qualify the call to format_to, i.e. change it to fmt::format_to: https://godbolt.org/z/3cYh3Gso9.

@vitaut Damn, I just sent the package for publication but we can fix it in the test then
well I'll make a revision, thanks!

Applied the workaround to the test in 3999fd1.
