Release v8.3.10

• (@GermanBluefox) Fixed: "REAUTHENTICATE!" log flood (#3110)
• (@GermanBluefox) Fixed: the "connection lost" overlay appears only after 2 seconds; loading a tab shows a spinner instead of it
• (@GermanBluefox) Updated @iobroker/gui-components to 10.4.3: the loader uses the background of the theme
• (@GermanBluefox) Updated @iobroker/json-config to 10.1.17: coordinates shows the position on an OpenStreetMap with map: true, a click on the map or dragging the marker sets it, mapStyle chooses the colors and readOnly only shows it; custom shows web components of @iobroker/web-components (webComponent); the text patterns know _instance. Admin provides the map, loaded only when a configuration shows one
