Site-www: Change Windows installer link to be https

[jonasfj]

The community supported Windows installer referenced in:

https://github.com/dart-lang/site-www/blob/a4b74d94bf0e94fafbaeb4af8e55f69ff4abf39b/src/tools/sdk/_windows.md#L50-L55

Only has an HTTP-only website (ie. without HTTPS support).

@GeKorm, is this still maintained? If so could we consider upgrading the website to HTTPS, or moving it to some static web host with HTTPS support.

Or maybe we should consider not advertising this installation method.

I just saw the github repository github.com/GeKorm/dart-windows, which has been updated fairly recent, so I assume this is still maintained.

@GeKorm, maybe it would be safer to host the website for the installer on github pages which has HTTPS?

[GeKorm]

Hi, it is indeed hosted on github pages. I'll look into enabling HTTPS, thanks

Edit: I changed the DNS settings, it will take up to a couple days until it's enabled for everyone. I'll update this thread when it's done.

If it's on GitHub pages it should just be an option to enforce HTTPS:

Thanks for looking into this :)

[GeKorm]

Yep those are the changes. Github used a different set of IPs for A records before that blog post

[GeKorm]

Should be good now, with http -> https redirection

Thanks, @GeKorm!
