Display supported Memos version in popup

Add a localized notice for supported Memos versions and render it in the extension popup. Introduce the "supportedMemosVersion" message in en and zh_CN (shows compatibility: v0.24.0+ and tested versions), add a corresponding div to popup.html, and wire it up in js/i18n.js so the text is populated via i18n.
