Remove the author copyright notices

[cakebaker]

This PR removes the author copyright notices from files missed by #5184

[tertsdiepraam]

Do you know why these were missed? Is the format slightly different? Maybe it's a good idea to completely standardize all the copyright notices?

[cakebaker]

The format is slightly different, they all use * in the comments.

It all seems to be a bit messy. Here are the first four lines of all the files in src that are not main.rs (thanks nushell!). I'd propose that we convert all to variant 0.

For reference, this is the nu command:

glob src/**/*.rs | filter { |it| not ($it | str ends-with "main.rs") } | each { |it| open --raw $it | lines | range 0..3 | str join "\n" } | uniq
