Add catalog classification

[by-night]

if I have two keys: account.label.name and device.label.name
Can it be configured in setting.js to achieve classification in the i18n ally of the vscode sidebar according to the form of directories, such as the following display mode:

• cn

  • account
    • account.label.nam
  • device
    • device.label.name

• en
  ...

  At present, it is only classified by language, and it is not very good to find
