Change winlibs from UCRT version

[shawnlaffan]

Per discussion in StrawberryPerl/Perl-Dist-Strawberry#56 (comment) and onwards.

We need to update the URL at

spbuild/5.34/Dockerfile

Line 18 in 68d953d

ADD https://github.com/brechtsanders/winlibs_mingw/releases/download/11.2.0-13.0.0-9.0.0-ucrt-r2/winlibs-x86_64-posix-seh-gcc-11.2.0-llvm-13.0.0-mingw-w64ucrt-9.0.0-r2.zip c:/Windows/temp

While we are at it, it might be useful to change the unpacked dir from /z/mingw64 to something like /z/winlibs to avoid confusion with /mingw64. This is one line in the docker file but will need other parts of the system to be updated.

Move-Item "C:/Windows/temp/winlibs/mingw64" "./mingw64"; `

Apologies, @shawnlaffan. It seems like I didn't have the permissions setup correctly on this repo for you to be able to commit, etc. Hopefully that's fixed now

All good. I haven't tried to push to this repo yet in any case.
