Publish GRIB codes to the WMO Codes Registry

[amilan17]

Details

During the face to face meeting (reference) the team decided to publish GRIB and BUFR codes to the WMO Codes Registry after every approved release.

Related issues: https://github.com/wmo-im/CCT/issues/171 and https://github.com/wmo-im/BUFR4/issues/212

Things to do:

1. Verify scope of effort
   1. publication artifact for use as-is, published PDF manual is still the authoritative source
   2. does not replace machine-readable-codes
   3. determine versioning in line with C-0 table (different from internal codes registry versioning) 
   4. initial effort does not attempt to build mapping to other registries in codes.wmo.int nor external vocabularies
2. Decide on the list of tables to upload
3. Create scripts to generate and upload the TTL files
