Synchronise requirements in the metanorma asciidoc files with those in the gpq validator

There is a need to synchronise requirements in the metanorma asciidoc files with those in the gpq validator.

GPQ validator checks right now are:

✓ file must include a "geo" metadata key
✓ metadata must be a JSON object
✓ metadata must include a "version" string
✓ metadata must include a "primary_column" string
✓ metadata must include a "columns" object
✓ column metadata must include the "primary_column" name
✓ column metadata must include a valid "encoding" string
✓ column metadata must include a "geometry_types" list
✓ optional "crs" must be null or a PROJJSON object
✓ optional "orientation" must be a valid string
✓ optional "edges" must be a valid string
✓ optional "bbox" must be an array of 4 or 6 numbers
✓ optional "epoch" must be a number
✓ geometry columns must not be grouped
✓ geometry columns must be stored using the BYTE_ARRAY parquet type
✓ geometry columns must be required or optional, not repeated
✓ all geometry values match the "encoding" metadata
✓ all geometry types must be included in the "geometry_types" metadata (if not empty)
✓ all polygon geometries must follow the "orientation" metadata (if present)
✓ all geometries must fall within the "bbox" metadata (if present)

So we should be sure that all of those have a 'requirement' in the asciidoc file. And also see if there's any requirements there now that should be in gpq or other validators.
