Use symfony/finder to find Requests within Subdirectories

[JonPurvis]

Fixes #53

This PR fixes the issue raised in the Issue above, in that when running php artisan saloon:list, if your files live in a subdirectory, then it doesn't find them and actually fails:

It didn't even occur to me that some applications would do this 😆

Fortunately, symfony/finder comes to the rescue and makes it easy to find files in directories. This PR basically just swaps usages of glob() to instead use symfony/finder. With this branch, if you run php artisan saloon:list, you now get the expected output:

Notice how my Requests live in subdirectories?

This PR actually makes a couple more changes:

• Finding Connector classes doesn't rely on them having Connector as the file name suffix e.g. StripeConnector.php. If I was to just name it Stripe.php, then that would also work
• I've opted to include the full path to the file in the output instead of just the filename.

Another one for you! 🤠

Apologies if you'd already started on this one, if that's the case, feel free to dismiss this PR!

Ah @JonPurvis you are a legend, thank you so much for doing both of these PRs! ❤️ It helps so much especially when I'm busy.

I'll have a look over the code but I'm sure it's great.

Code looks really good. I should probably invest in some proper tests for commands but for now I'll test it manually

I love Saloon, use it every day, always happy to help out where I can! Especially when it's my initial code that has the issue 😆 I've never used symfony/finder before so it was cool getting to grips with a new package!

Thanks man, as always it means a lot <3

and yeah, Symfony Finder is super cool, and comes installed in Laravel by default!
