New heuristic for no-untranslated-string: catch all label props? #100

Problem

A few untranslated strings in JupyterLab were missed, two noted in jupyterlab/jupyterlab#19318:

        return new NotebookMetadataField({
          editorFactory,
          tracker,
          label: 'Notebook metadata',
          translator: translator
        }).render(props);

Proposed Solution

Should we flag all label: string-literal as possible missing translation?

Maybe this could be an option in no-untranslated-string.

Additional context

None
