update-microsoft-git: Windows implementation

On Windows, we have the 'git update-git-for-windows' command. It is poorly named within the microsoft/git fork, because the script has been updated to look at the GitHub releases of microsoft/git, not git-for-windows/git. Still, it handles all the complicated details about downloading, verifying, and running the installer. Signed-off-by: Derrick Stolee <[email protected]>
