Check if build time is set

[grappler]

I came across the problem where the translations were not updating as the "updated" value was false which caused WP-CLI to save the translations zip without an updated time. This meant there was always an update for the plugin but it was not really updated.

This problem arose as the zip files were created before the new feature for the updated time was added. I think it is better to be cautious and not show the zip information if crucial data is missing.

This shouldn‘t happen nowadays, right? Should we perhaps queue another build if the meta data is missing?

Yes, but I am not sure if there will be cases where the value is not valid when set https://github.com/wearerequired/traduttore/blob/6655e70fbd0abf52bc93d9542a5520d379df83fe/inc/ZipProvider.php#L131

That would be a good idea. Here is another example: https://translate.required.com/api/translations/foodward/foodward-post-types/
