Updated Dutch translations

[evertharmeling]

As asked on Slack

• Ran bin/console translation:extract --force nl command, this caused the major update in the file. But I guess it should be the recommended way to extract the translations.
  • Running the command also added separate security and validators files. If everybody uses the command above it may be logical to add them and have control over them in the demo application. Otherwise we could explicitly not add them as they seemed to be correctly translated already? For now not added the extra generated files, this could be done later on for every language if we decide to.
• Added missing label.remember_me (for en and nl)

Thanks for this. The validators.nl.xlf and security.nl.xlf files look the same as the default Symfony files, right?

I think we should exclude them, but let's wait for more comments about this. Thanks!

Looking at:

• default validators.nl.xlf it does not exactly match the one in this PR.
• default security.nl.xlf also does not exactly match the one in this PR (it's 1 translation off in count, didn't diff it on identifier)

Not sure how it's exactly generated, but maybe good idea to exclude them idd.

Removed the extra generated files so we can move this PR forward, we could always add those files by running the command again 😊

EDIT: I've also re-extracted the translations for en, so I could make a clean diff on nl vs en translations, those are now in sync and (should be) complete.

EDIT 2: Since the extraction of the translations aren't ordered and this is only supported via the --dump-messages option, the easiest way is to generate 2 outputs bin/console translation:extract --dump-messages <lang> (one for en and your language) and compare which identifiers are missing.

tip: In PHPStorm you may easily diff the files by selecting them and press cmd + d (on mac)
