[Send PRs] to replace http by https in the github url of the repository in Cargo.toml

[szabgab]

On the Crates in Repo with http there are 355 crates listed that have http://github.com in the repository field in Cargo.toml. It is not a big issue as github redirects to https://github.com anyway, but fixing this helps my brain.

OK, this might not be a huge help to the Rust Ecosystem, but still, if you like the Rust-digger and in general my contribution to the Rust ecosystem, please consider supporting me via GitHub sponsors.

Sent PR to all the crates last released in 2020. Probably they won't be released again any time soon, but if they get released this could be already fixed for them.
