Update the index squashing script to push snapshot branches to this repo instead

[carols10cents]

After:

• Transfer this repo to the rust-lang org #1

I haven't looked for the index squashing script yet, if someone knows where it is and could drop a link that would be helpful.

I'm happy to do this once the admin tasks are completed.

The squash code is here: https://github.com/rust-lang/crates.io/blob/9744a25a6c8e0adead72dc54f6d90faf14da6800/src/worker/git.rs#L86-L120

We can leave one snapshot branch around for about a week or even a bit longer. So my current plan is to update the squashing code to:

• Do what it currently does
• Push the previous snapshot branch to the archive repo
• Delete the previous snapshot branch

Thoughts?

Seems reasonable to me, thanks for looking into it!
