Please design custom variables for the default layer as OpenStreetMap,

[dfwsbylwy]

Before, when a new data package was opened, Qfield would add the default layer openstreetmap(### QStringLiteral( "type=xyz&url=https://a.tile.openstreetmap.org/%7Bz%7D/%7Bx%7D/%7By%7D.png&zmax=19&zmin=0&crs=EPSG3857" ), QStringLiteral( "OpenStreetMap" ), QLatin1String( "wms" ) )) to the layer. However, I hope that the XYZ online layer network address of this default layer can be customized, which will be more suitable, convenient and wider for users.
