Add windows installation script

[Veetaha]

ChatGPT rules.However of course it made a ton of mistakes converting bash to powershell, and I of course I had to stare at powershell syntax with their poor error messages for some time. But, anyway, it's past that and the script works.

You can test it using a separate branch where I configured it to work with my fork.

curl.exe --location --silent --fail --show-error --retry 5 --retry-connrefused `
    https://raw.githubusercontent.com/Veetaha/marker/feat/install-on-windows-test/scripts/release/install.ps1 | powershell -command -

This was inspired by the installation script in deno. Turns out both curl.exe and tar.exe are available on windows by default, and deno also uses them for its installation script.

There are some stupid caveats with using unicode symbols (I'm not even saying ansi colors) on windows. I didn't look into that, and just made the script monochrome and use > character for logging the executed commands.

I didn't update the docs here. I think I'll just make separate PR for that whicj will also include the commit with the docs for linux

Also fixed the behavior of install.sh when the $CARGO_HOME variable is set. Previously it was writing directly to it, but instead it has to write to a $CARGO_HOME/bin subdirectory.

UPD
I just made the script work on linux too. It's possible to install powershell on linux. The only thing is that I had to add a condition that adds .exe to curl command on windows (due to a really stupid windows design decision described in code comment). So now it's possible to test the script on linux as well.

An important caveat is that you'll likely install the latest PowerShell 7.0 on linux, but on real Windows 10/11 the version of powershell is quite old (5.1), so don't try to use any new features.

Looks good to me. I've tested it on a Windows computer, and it worked perfectly. Thank you for this!

Also, I have to say: I love the comments ^^ It makes reviewing the changes a lot more fun ❤️
