export Translation data in webform's YAML configuration file

I think you cant export webform translations in Drupal 10 when you export a webform's YAML configuration file.
However, you can only export webforms as YAML files, which can be used to transfer webforms between environments.

A side note: As far as I can tell, imports and exports of .po files from Drupal core storage seems buggy (so I see no solution in Drupal core for this issue); I could not export as a .po file the French translation of a webform initially created in English. (Maybe I'm doing it wrong?)

Steps to reproduce

Install config_translation_po module Version: 1.0.1

Create a webform in English with this source:

some_checkbox:
  '#type': checkbox
  '#title': 'Some Checkbox'
  '#description': '<p>Some description here.</p>'

Use the UI for webforms translation, into French. Test that it works ok for both languages. (/en/ or /fr/ in URL).

Do an export of French translation,
from /en/admin/config/regional/translate/export,
it exports empty msgstr ""

Do an export of French translation,
from /en/admin/config/regional/config-translation/export,
it exports English msgstr ""
