Registry URL validation doesn't match template guidance

[jaydeluca]

What happened?

When adding a new registry entry, and following the template, the comments seems to indicate that the repo input is the only mandatory URL:

urls:
  repo: https://github.com/your-organization/your-repo # (mandatory) projects don't have to be hosted on GitHub, but this should link to the git or other source control repository for your project
  docs: https://your-organization/your-instructions # (optional) path to a documentation for the specific project.

However, if you only specify the repo, you get the following errors when trying to build and run the project:

ERROR Website URL is missing for integrations registry entry 'JDBI'
ERROR Docs URL is missing for integrations registry entry 'JDBI'

What did you expect would happen?

Should the template be updated to indicate that all three fields are mandatory? Or should we update this validation to allow them to be left blank?
