raster_to_vector produces a geojson file with the wrong crs

[JeroenVerstraelen]

Example:

import openeo
from openeo.rest.datacube import DataCube
from openeo.rest.datacube import UDF

connection = openeo.connect("openeo-dev.vito.be").authenticate_oidc()
bbox = [5.0, 51.2, 5.1, 51.3]
temp_ext = ["2023-01-01", "2023-01-20"]

s2_bands = connection.load_collection(
    "SENTINEL2_L2A", spatial_extent=dict(zip(["west", "south", "east", "north"], bbox)), temporal_extent=temp_ext, bands=["SCL"]
)

scl_band = s2_bands.band("SCL")
s2_cloudmask = ( (scl_band == 1) ) * 1.0

vector = s2_cloudmask.raster_to_vector()
vector.download("s2_cloudmask.geojson", format="geojson")

The features are in 32632 projection, but the FeatureCollection has CRS84 as crs.
