Default to LANG setting for locale

[jawnsy]

@oxy explained how code-server's localizations work:

FWIW on code-server's side we have localizations working; all that's needed is F1 -> Configure Display Language -> Install additional languages -> selecting from extensions for manual changes.

This could be something that can be automated on the enterprise side by code-server --install-extension ms-ceintl.vscode-language-pack-fr and then writing {"locale": "fr"} to ~/.local/share/code-server/User/argv.json - though I haven't touched any of the enterprise code so I don't know how possible that would be

(replace fr with two letter language code as applicable)

As an alternative to writing files, it would be nice if we can instead parse the LANG environment variable (e.g. LANG=en_US.utf8) and default to that. The existing behavior should still take priority as users may want to override the locale (e.g. a Spanish-speaking user that uses an English UI, but wants to use Spanish in their editor).

I also tried to automate the Portuguese language by installing the extension and setting the locale to no avail. I installed the MS-CEINTL.vscode-language-pack-pt-BR-1.57.2.vsix package and set "locale": "pt-br" in the argv.json file but it doesn't automatically start in the desired language. However, if you install this same package, through the option install extension from vsix file (within the code-server) it works.

Do you have any suggestions or is it a bug?

Could be an extension bug then. We're working on switching over to Open VSX so it may be fixed after that!
