Linkerd2: Add locales to Linkerd web dashboard

[scottcarol]

Feature Request

What problem are you trying to solve?

The web dashboard for Linkerd now has en and es translations. This can be expanded to other languages.

How should the problem be solved?

To add a new locale, follow the local development instructions in BUILD.md. Then, from your command line:

cd web/app
yarn lingui add-locale [locales...]

This will create a your-new-locale/messages.json file for new locale(s), that will automatically have all existing keys. Once you have edited that new messages.json file, you can run yarn lingui compile and view on your web browser in the language of your choice.

@scottcarol Just want to make sure I understand the scope, is there a list of locales we want to include as part of this issue? Or is this more a doc update? Or do we want to introduce a new script etc.?

Per conversation with @scottcarol, the purpose of this issue is to promote visibility of the process to add more locales to the Linkerd dashboard, following interests in KubeCon. We agree that this info should be added to the Linkerd doc. I will follow up with a separate doc PR.

I am happy to work on the French translation - unless it's better to wait for a locales that are desired / needed, as you've mentioned @ihcsim?
