[bug]: Translations unusable and saved without plugin prefix

[joaovpmamede]

What version of @strapi/sdk-plugin are you using?

Npm version
9.8.1
Node.js version
18.18.2
React version:
18.3.1
@strapi/sdk-plugin version
5.3.1

What's Wrong?

My understanding is that a plugin should use translations with the plugin name as a prefix, hence the use of PLUGIN_ID to get the translation.
It seems that before a prefixPluginTranslations function was used to "add" the prefix to each translated string (e.g. users-permissions plugin).

To Reproduce

We can see that this is not working because there's no functionality to add this prefix.
We can also check the messages object from the useIntl() hook to see how its being saved (after adding some strings to /translations/en.json for example).

Expected Behaviour

The getTranslation function should return the correct string for the current locale.
