Incorrect path construction in generate_kerchunk_stac Method

[E-O-Conchas]

The generate_kerchunk_stac method in the Raster2STAC class constructs output file paths incorrectly, causing a FileNotFoundError. This seems to happen due to improper concatenation of paths.

`An error occurred: [Errno 2] No such file or directory: 'S:\ebv_portal\kerchunk\test-data\output_test\kerchunk/S:\ebv_portal\kerchunk\test-data\sp_2001_crs.nc.json''

Hi @E-O-Conchas, are you using it on Windows? That's probably the root of the problem. I will try to fix it and let you know!

Update: I just tried the Kerchunk example in the Readme and for me it works fine also on Windows. Could you give me some more details? In which part of the code is the error occurring?
