Subject: [PATCH] Update reindeer to look for cargo lock version 4

Summary:
1.83.0 uses version 4 for cargo lockfile. Lockfile v4 was stabilized in 1.78.0.

https://github.com/rust-lang/cargo/blob/master/src/cargo/core/resolver/resolve.rs#L89-L95

Adds awareness of url encoding to SourceId, which AFAICT does not impact any Meta-internal usages of rust today?
