Auto export translation keys

[KDederichs]

Short description of what this feature will allow to do:
I don't know if it's even possible but it'd be awesome if EA could hook itself into the Translators extract command and export all the entity labels (either explicitly set or inferred by property name)

Example of how to use this feature
It would make translating the admin a lot easier since you don't have to go around and pick up all the translation keys.

Yes, this would be a nice idea. I think we need this:

(1) Symfony should provide a mechanism for third-party bundles to add translations to the catalogs. I don't know if this already exists or not and if it provides all the features we'd need or not.
(2) If this mechanism exists, let's use it in this bundle to ease translating backends.

@KDederichs could you please check if (1) already exists in Symfony? Thanks!

From the looks of it the way to go here would be to implement a custom Extractor (https://github.com/symfony/translation/blob/7.2/Extractor/ExtractorInterface.php) and then use that to push all the messages into.
Tested it locally and it seems pretty straight forward to set up, just implement the interface and tag it like this:

#[AutoconfigureTag(name: 'translation.extractor', attributes: ['alias' => 'test.extractor'])]

The main issue would be getting all the translatable things out of EA but maybe you'd have a better grasp on how to handle that one.
