Add i18n to JupyterLab

[blairdrummond]

Look into whether the JupyterLab UI can be offered in other languages.

• i18n (including extensions) - finish FR language pack + use KF_LANG to set language on startup
• Debugger - xpython
• Extensions - use compatible versions
• Docker Stacks - check for new release wih Jupyterlab 3.0. upstream issue: JupyterLab 3.0 jupyter/docker-stacks#1207

[wg102]

The feature i18n and i10n (jupyterlab/jupyterlab#3965) is planned to be part of the 3.0 release (jupyterlab/jupyterlab#8038), which has no clear release date.
The i18n PR is rather extensive (jupyterlab/jupyterlab#8800).

The second part is having the translations (https://github.com/jupyterlab/language-packs), this is the issue for the Translations jupyterlab/jupyterlab#8829
which mentions the translations are done through crowdin. We will need those to be completed before we can use the language pack. https://crowdin.com/project/jupyterlab

I suggest to wait until this is merged and released before investigating if all our needs are met, and how to set the languages we want.

@JessicaBarh it seems jupyterlab-theme-solarized-dark is supported on the 3.0.x line?

However I don't even think we use it anymore (not using solarized):

@blairdrummond did we also add the french language pack for code-server (vscode)?

[blairdrummond]

@Ito-Matsuda has been looking at that I think?

[Jose-Matsuda]

I added it for kubeflow-containers-desktop yes. (Note that this PR incorrectly used the Microsoft marketplace version. I later made a PR to fix that by grabbing and building the extension from the French Language package git repo)

[blairdrummond]

@Ito-Matsuda would you be able to take on that functionality for the kubeflow-containers? Should be the same process right?

[Jose-Matsuda]

Yea adding it should be no problem.

@blairdrummond this is just adding the language pack correct? I'm looking at how we installed the python and r extension and after testing adding the following
code-server --install-extension MS_CEINTL.vscode-language-pack-fr
get's the job done and the French language pack is installed.
