Suppress UnusedClass/PossiblyUnusedMethod on well-known classes/methods of fresh Laravel/Lumen projects

Fixes #53.

I wonder if these are still emitted if the bootstrap/app.php file is analyzed? Thinking out loud..

[caugner]

Good point, bootstrap/app.php does use App\Console\Kernel, App\Exceptions\Handler and App\Http\Kernel. And some of the other classes are used in config/app.php.

So maybe it is worth adding those directories to the tests/(laravel|lumen)-test-psalm.xml configs. 🤔

In my project, I have configured <projectFiles> likes this, probably due to too many errors (and some of this could explain some of the weird errors I have experienced):

    <projectFiles>
        <directory name="."/>
        <ignoreFiles allowMissingFiles="true">
            <directory name="app/Http/Middleware"/>
            <directory name="bootstrap/cache"/>
            <directory name="cache"/>
            <directory name="config"/>
            <directory name="database"/>
            <directory name="node_modules"/>
            <directory name="routes"/>
            <directory name="storage"/>
            <directory name="tests"/>
            <directory name="vendor"/>
            <directory name="vendor-bin"/>
            <file name="bootstrap/app.php"/>
            <file name="public/index.php"/>
            <file name="server.php"/>
        </ignoreFiles>
    </projectFiles>

edit: Ideally, we would support as much files as possible, and make a recommendation in the README.

yep, didn't view that as a blocker for this PR, but something we should consider!

This is awesome! Thanks a lot for your help
