Version-specific channel-*.toml files missing when creating new mirror #135
Description
Hello!
I noticed that when setting up a new Panamax mirror, the version-specific .toml files for the Rust toolchains (e.g. dist/channel-rust-1.79.0.toml) aren't being created. When using keep_latest_stables = 1 I was expecting to see the following files (based on 1.79.0 being the latest Rust stable version at the time of this writing):
channel-rust-1.79.0.tomlchannel-rust-1.79.tomlchannel-rust-stable.toml
But the only one that seems to get created is channel-rust-stable.toml.
