Update to new l10n (#20484)

Following
https://github.com/microsoft/vscode-engineering/wiki/Extensions-Localization

This onboards vscode-python to the new localization API which enables
localization for the web.

It's a large PR ... but pretty boring since it's just replacing one
syntax with another.
