Symfony 5 compatibility

[gaea44]

Hi,

just updated my project from symfony 4.3 to symfony 5.0, but behat/symfony2-extension doesn't seem to be working with.

"require": {
    "php": "^7.2.5",
    "ext-ctype": "*",
    "ext-iconv": "*",
    "sensio/framework-extra-bundle": "^5.1",
    "symfony/asset": "5.0.*",
    "symfony/console": "5.0.*",
    "symfony/dotenv": "5.0.*",
    "symfony/expression-language": "5.0.*",
    "symfony/flex": "^1.3.1",
    "symfony/form": "5.0.*",
    "symfony/framework-bundle": "5.0.*",
    "symfony/http-client": "5.0.*",
    "symfony/intl": "5.0.*",
    "symfony/mailer": "5.0.*",
    "symfony/monolog-bundle": "^3.1",
    "symfony/notifier": "5.0.*",
    "symfony/orm-pack": "*",
    "symfony/process": "5.0.*",
    "symfony/security-bundle": "5.0.*",
    "symfony/serializer-pack": "*",
    "symfony/string": "5.0.*",
    "symfony/translation": "5.0.*",
    "symfony/twig-pack": "*",
    "symfony/validator": "5.0.*",
    "symfony/web-link": "5.0.*",
    "symfony/yaml": "5.0.*"
  },
  "require-dev": {
    "behat/mink": "dev-master",
    "behat/mink-extension": "^2.3",
    "behat/mink-goutte-driver": "^1.2",
    "behat/mink-selenium2-driver": "^1.3",
    "behat/symfony2-extension": "^2.1",
    "roave/security-advisories": "dev-master",
    "symfony/debug-pack": "*",
    "symfony/maker-bundle": "^1.0",
    "symfony/profiler-pack": "*",
    "symfony/test-pack": "*"
  },

here is the error :

behat/symfony2-extension 2.1.5 requires symfony/framework-bundle ~2.0|~3.0|~4.0 -> satisfiable by symfony/framework-bundle[v4.3.8] but these conflict with your requirements or minimum-stability.
