Changes at "Multilingual organization name"

Is your feature request related to a problem? Please describe.
In some multilingual instances, we need to have the service name in the target language selected by the user. Currently Decidim system panel only allows defining a single locale.

Describe the solution you'd like
I would like to have the possibility to define the organization's name in multiple language rather than limiting it to only a single language. This change should apply to both, the system panel as well as the admin pane's organization edit view.

Describe alternatives you've considered
Hacking it to the template, cumbersome if we want to use the same code for other service too (like we do, the actual service and the Youth budget).

Additional context
This is an actual requirement in the service we are building.

Does this issue could impact on users private data?
No.
