Giving microsoft/git it's own README

[ldennington]

It's probably time to customize this for microsoft/git 😀. Plus I have to add instructions to be able to close out these issues:

• https://github.com/github/git-client/issues/357
• https://github.com/github/git-client/issues/357

I suggested some changes, but because they contain ranges with three tick-marks, the web renderer is broken (it uses the tick marks, too, but doesn't recognize nesting).

You can see the full markdown for the suggestions by "editing" the comments, if you want.

This is probably the safest thing to do, although I found it simplest to go to the microsoft/winget-cli releases page and get the latest version.

Even that was a little confusing, because I've never installed a .appxbundle file before.

🤦🏻 I just saw these comments. Addressing in a followup PR.

Suggested change

	wget https://github.com/microsoft/git/releases/download/v2.31.1.vfs.0.1/git-vfs_2.31.1.vfs.0.1.deb microsoft-git.deb
	sudo dpkg -i microsoft-git.deb
	wget -o microsoft-git.deb https://github.com/microsoft/git/releases/download/v2.31.1.vfs.0.1/git-vfs_2.31.1.vfs.0.1.deb
	sudo dpkg -i microsoft-git.deb

I apologize that I was incorrect in remembering the wget -o option. I think it is easier to use this so a user only needs to modify the version string in one place.

(This makes me want to create a workflow that triggers on a new release to replace this version string and create a PR. But that can wait until I'm really bored.)
