Subject: [PATCH] QgsRasterFileWriter::driverForExtension(): make sure querying
 the tif/tiff extension returns the GTiff driver

Not strictly necessary since has been adressed on GDAL side per https://github.com/OSGeo/gdal/pull/11037
but might be prudent for future similar situations.

Fixes #59112
