ux: clone: make `<DIRECTORY>` optional

[Dentrax]

Summary 💡

clone command requires <DIRECTORY> argument, which I think it should be optional instead: [<DIRECTORY>]:

git way:

git clone [OPTIONS] <repository> [<directory>]

gix way:

gix clone [OPTIONS] <REMOTE> <DIRECTORY>

Motivation 🔦

git by default uses the project name when creating folders. Whereas gix, we have to pass manually, which makes the UX a bit slower. (since we have to copy-paste the repository name)

The following command should just work:

$ gix clone git@github.com:Byron/gitoxide.git
error: The following required arguments were not provided:
    <DIRECTORY>

We can easily get the <DIRECTORY> from the repository name, which is gitoxide in this case.

Thanks for bringing it up. As gix is a development tool best ux isn't one of its goals - that is only true for ein which is incumbent at best.

That said, as it's easy enough to implement this well enough, I have implemented it now. Please note that git applies more logic than is currently implemented so the results may differ in some less common cases. Also, I fixed a bug that would make it possible to deadlock clones with ssh urls, thus you might want to build a fresh gix from main.

Wow, thanks for such prompt action!
