Remove orphaned gettingStartedModal translation keys from all locale files

[Copilot]

After the GettingStartedModal refactor (PR #138), the old list-based keys (list.one.label, list.two.label, list.three.label, list.four.label, seeAction.*, editorBasics.heading, editorBasics.list.label) were removed from pt-BR.json but left orphaned in all other locale files.

Changes

• Removed orphaned keys from all 8 locale files (de, en, es, fr, it, pt-BR, pt, ro)
• Preserved active keys still used by the component: list.paragraph, list.paragraph2, list.paragraph3, list.paragraph4, list.faq, list.imageEddie

Keys removed per file (9 in most, 8 in pt-BR which already lacked list.label):

editor.gettingStartedModal.editorBasics.heading
editor.gettingStartedModal.editorBasics.list.four.label
editor.gettingStartedModal.editorBasics.list.label
editor.gettingStartedModal.editorBasics.list.one.label
editor.gettingStartedModal.editorBasics.list.three.label
editor.gettingStartedModal.editorBasics.list.two.label
editor.gettingStartedModal.seeAction.item.label
editor.gettingStartedModal.seeAction.label
editor.gettingStartedModal.seeAction.time
