Description
Hi, i was trying ./mill init with mill 0.12.10 (and also a 0.13 version) on my multi module maven project (with wsl linux). I get the following stack trace
[1/1] init
[7/7] mill.init.InitMavenModule.init
[7] converting Maven build
[7] Exception in thread "main" os.PathError$InvalidSegment: [../backend-api] is not a valid path segment. [/] is not a valid character to appear in a non-literal path segment. If you are dealing with dynamic path-strings coming from external sources, use the Path(...)/RelPath(...)/SubPath(...) constructor calls to convert them.

As seen in the stack trace, it's a multi module build with modules defined like this in the parent module:
<modules>
<module>../backend-api</module>
</modules>
I hope this is an actual bug and not something that's not supposed to be supported, since I was just playing around. I haven't really looked around in the source yet since I am just learning scala.
