Issue in gdal.Grid called from python bindings about gdal

[rouault]

The code used to work up to gdal 3.8.5,

Weird. It should not. radius1, radius2 or nodata (lower case) are not accepted parameters. They should be put inside the algorithm string. Cf:

    """ Create a GridOptions() object that can be passed to gdal.Grid()

    Parameters
    ----------
    options:
        can be be an array of strings, a string or let empty and filled from other keywords.
    format:
        output format ("GTiff", etc...)
    outputType:
        output type (gdalconst.GDT_Byte, etc...)
    width:
        width of the output raster in pixel
    height:
        height of the output raster in pixel
    creationOptions:
        list or dict of creation options
    outputBounds:
        assigned output bounds:
        [ulx, uly, lrx, lry]
    outputSRS:
        assigned output SRS
    noData:
        nodata value
    algorithm:
        e.g "invdist:power=2.0:smoothing=0.0:radius1=0.0:radius2=0.0:angle=0.0:max_points=0:min_points=0:nodata=0.0"
    layers:
        list of layers to convert
    SQLStatement:
        SQL statement to apply to the source dataset
    where:
        WHERE clause to apply to source layer(s)
    spatFilter:
        spatial filter as (minX, minY, maxX, maxY) bounding box
    zfield:
        Identifies an attribute field on the features to be used to get a Z value from.
        This value overrides Z value read from feature geometry record.
    z_increase:
        Addition to the attribute field on the features to be used to get a Z value from.
        The addition should be the same unit as Z value. The result value will be
        Z value + Z increase value. The default value is 0.
    z_multiply:
        Multiplication ratio for Z field. This can be used for shift from e.g. foot to meters
        or from  elevation to deep. The result value will be
        (Z value + Z increase value) * Z multiply value. The default value is 1.
    callback:
        callback method
    callback_data:
        user data for callback
    """

There has been no change in the gdal.GridOptions() signature between 3.8.5 and 3.9.0
