Update STAC projection extension

[danlooo]

This PR fixes outdated schema of STAC extension projection.

The formerly deprecated field proj:espg was removed in favor of proj:code.
A former "proj:epsg": 3857 is now "proj:code": "EPSG:3857".
see https://github.com/stac-extensions/projection/releases/tag/v2.0.0 as of Jul 22, 2024

      "result": true
    }
  }
}

results into ValueError: The asset must have the following fields (from the projection extension): shape, transform, and one of an epsg, wkt2, or projjson

Solution

Pystac needs to be >=v1.12 see https://github.com/stac-utils/pystac/releases/tag/v1.12.0
