Wrong media type for COGs

[m-mohr]

I have a Batch job result which points to a valid COG (checked with rio-cogeo), but the media type is set to a "regular" GeoTiff. This means that the Web Editor, STAC Browser, etc. often avoid loading the data as it assumes it's too large for memory.

If you expose a COG (great!) then the media type should be image/tiff; application=geotiff; profile=cloud-optimized instead of image/tiff; application=geotiff.

Example:

[jdries]

@ElienVandermaesenVITO can you verify if this media type is set correctly for stac 1.1 output? That would be an easy backwards compatible way to fix this.

[ElienVandermaesenVITO]

The media type is currently still the same for stac 1.1, so this should still be done.
