Move viewer language selector in Brand Navbar as is for all other app pages

[tdipisa]

Description

We need to ensure the language plugin is included inside the BrandNavbar of the map viewer. At the moment the map viewer is displaying the language selector inside the Settings plugin (it should be a configuration change).

Initial investigation:

• Settings plugin includes a LangBar component that seems to be configurable. We should set this disable by default and verify we can actually configure it via localConfig.json
• Include the Language plugin in desktop (map viewer) configuration of localConfig.json { name: "Language" }
• Include the Language plugin to the pluginsConfig.json

What kind of improvement you want to add? (check one with "x", remove the others)

• Minor changes to existing features
