Update rdls_schema.json

[stufraser1]

Dataset Identifier URL pointing to readthedocs version of docs and codelists location, which does not give correct guidance. Replaced with correct location of guidance relevant to the field (how to complete dataset identifier)

Merge checklist

If you added, removed or renamed a field:

• Update the collapse option of the jsonschema directives for dataset, resource, hazard, exposure, vulnerability and loss on reference/schema.md
• Update the diagrams in reference/schema/md
• Update the JSON files in examples

Always:

• Run ./manage.py pre-commit
• Update the changelog (style guide)
