[Cleanup] "Get Started" page - Broken download links for mac/windows/linux builds

[zamzx]

What needs to be cleaned up?
https://docs.themirror.space/docs/open-source-code/get-started

Currently` if you try to download any build you get this error message :

`This XML file does not appear to have any style information associated with it. The document tree is shown below.

NoSuchKey
The specified key does not exist.

No such object: mirror_native_client_builds/Engine/e33f01e3/MirrorGodotEditorLinux.x86_64

`

Can you do this yourself? Contributions are greatly appreciated!

I can't fix it, I just got here! :)

Cheers!
