Introduce a translation:check-missing command

[nicwortel]

Fixes #388.

I don't believe the PHPStan error is introduced by my pull request.

-- ------------------------------------------------------------------------- 
    Error

    Ignored error pattern #^Call to method getValue\(\) on an unknown class

    /github/workspace/Controller/SymfonyProfilerController.php was not       
    matched in reported errors.

I believe this is caused by an ignored error (in phpstan-baseline.neon) that is no longer reported. I could remove the offending lines from phpstan-baseline.neon.

I could remove the offending lines from phpstan-baseline.neon.

Looks like it's removed as part of #396 here: https://github.com/php-translation/symfony-bundle/pull/396/files#diff-cbcd91b5fa0a393ebd972f66cc47dc90

[nicwortel]

@Guite you are right. #396 is closed but #395 has fixed the build, so after merging master all checks are green.

My PR is now ready to be reviewed.

Except the name of the command, LGTM 👍 thanks for your work!

[welcoMattic]

@php-translation/deciders ok for you? We could target a 0.12 with this new command?

[odolbeau]

I think it's not needed when defining the static property.

[nicwortel]

I believe you are right, the Symfony documentation example also doesn't call setName() anymore.

However, I copied this from the other commands in this bundle which also call ->setName(self::$defaultName). So perhaps this should be fixed for all commands at once in a separate PR.

[nicwortel]

Are we waiting for more approvals, or is there anything I should do to get this merged? :)

[welcoMattic]

@nicwortel it's merged, we will release the 0.12 as soon as possible 😉

[nicwortel]

Nice 👍 I will try to find some time to create a PR for https://github.com/php-translation/documentation.
