Subject: [PATCH] Handle case of .mill-version with Windows line ends (#3975)

This is a precaution for cases when the `.mill-version` file can contain
a Windows line end `\r\n` instead of the typical Unix line end `\n`.
Without this fix, in such situation the script breaks in a spectacular
and surprising way.

The error it was giving looked like this:
```sh
$ mill __.compile
curl: (3) URL using bad/illegal format or missing URL
```
Where `mill` is pointing to the wrapper script that I'm changing in this
