Update micromamba installation docs for Windows

[Tiksagol]

No need to use 7zip as Windows 10 contains tar.exe (and the former might not be installed).

@Tiksagol does it really? I haven't really seen that in the wild (except on CI systems that is indeed the case).

I think we're working more towards putting the non-compressed binary somewhere so that installation becomes even simpler.

To that end, want to deploy this script? #2164 (comment)

@wolfv - yes, works fine on Windows 10

I think it ships bsdtar. You can see usage in the provision-with-micromamba code, which is compatible with bare bones Windows systems.

So I guess it's true! I'm fine with changing it to curl + tar in that case and keep the old one as reference for older systems.

@jonashaag - right:

C:\Users\me>tar --version bsdtar 3.5.2 - libarchive 3.5.2 zlib/1.2.5.f-ipp bz2lib/1.0.6

Hmmmmm, can you double check this for me?

On a windows server installation I can access, teh windows shipped tar doesn't have bzip2 support (see screenshot).

Seems like it has, as in my laptop it works and returned the same output (its end seems to be removed from your screenshot) -

c:\Windows\System32>.\tar.exe --version
bsdtar 3.5.2 - libarchive 3.5.2 zlib/1.2.5.f-ipp bz2lib/1.0.6
