Accountability components name customization lack consistency with other components

[andreslucena]

Describe the bug

As an admin, when I configure a new accountability component I can define the names for the models.

To Reproduce

1. Log in as admin
2. Create a new process
3. Create a new accountability component
4. See the form

Expected behavior

This isn't consistent with the rest of the application, as I can't define the names for the Proposals for instance (only the component name).

Officially we have 2 ways for customizing texts (and this isn't one of them): https://docs.decidim.org/en/develop/customize/texts.html

Additional context

We should add instructions in the releases notes so implementers can migrate to the other customizations options if they have already defined anything here.
