[network] Fix missing translations for filter hover text

The filter button's hover text in the Network panel was not being properly internationalized. The text remained in English even when other UI elements were translated. This change ensures consistent translation by properly configuring i18nString, allowing the hover text to be displayed in the user's selected language.
