feat: unlock intellisense for the finder component

[hirasso]

Solves #1097

Before

use Isolated\Symfony\Component\Finder\Finder;

return [
    'finders' => [
        Finder::create()->files()->in('src'),
        // ...
    ],
]

After

/** @var Symfony\Component\Finder\Finder $finder */
$finder = Isolated\Symfony\Component\Finder\Finder::class;

return [
    'finders' => [
        $finder::create()->files()->in('src'),
        // ...
    ],
]

• Update usage examples in all .md files
• Update scoper.inc.php.tpl
• Leave other instances untouched (fixtures, for example)

Notes

A few unrelated (whitespace only) formatting things slipped through in this PR. An .editorconfig or an automated lint step in a GitHub workflow would solve these kinds of issues and would make it easier for people to contribute to php-scoper. In my experience, an .editorconfig is usually enough.

Thank you @hirasso!

I don't mind someone proposing an .editorconfig, but I don't bother actively adding one either.
