0.12.2 requires unreleased Symfony packages

[Bjorn Post]

Hi,

b74f88e updated composer.json:

"symfony/twig-bundle": "^3.4.47 || ^4.4.20 || ^5.2.5",
"symfony/finder": "^3.4.47 || ^4.4.20 || ^5.2.5",
"symfony/intl": "^3.4.47 || ^4.4.20 || ^5.2.5",

But version 5.2.5 does not exist for these packages, 5.2.4 is the latest:

https://packagist.org/packages/symfony/twig-bundle
https://packagist.org/packages/symfony/finder
https://packagist.org/packages/symfony/intl

This currently results in 0.12.2 being uninstallable with minimum-stability >dev.
