So you just need to rename that text only? I ask because it looks like it is in the NLS settings so changing browser language should change that as well.
layerInfosMenu: {
titleBasemap: "Basemaps",
titleLayers: "Operational layers",
labelLayer: "Layer name",
itemZoomTo: "Zoom to",
itemTransparency: "Transparency",
itemTransparent: "Transparent",
itemOpaque: "Opaque",
itemMoveUp: "Move up",
itemMoveDown: "Move down",
itemDesc: "Description",
itemDownload: "Download",
itemToAttributeTable: "View in Attribute Table"
