Add Validation Endpoint for Records in InspireHEP

[drjova]

We need to add a validation endpoint to the InspireHEP service to validate different types of records, specifically for author workflows. The endpoint should accept a record as a payload and validate it according to the specified type.

TECH NOTES

• Add a new endpoint in the class AuthorWorkflowViewSet(viewsets.ViewSet) located here.
• The endpoint should be a POST request to /api/workflows/authors/validate.
• The endpoint should receive a record as the payload and perform validation using the get_validation_errors method from the inspire_schemas.utils package (ensure inspire_schemas is installed). You can reference the usage of this method in the record class here.
• Integrate the validation check when creating or updating an author workflow.
• Update the record editor to use this new endpoint instead of the existing /validate_workflow endpoint for author submissions.

Expected Behavior:

• If the record validation fails, the endpoint should respond with a 400 status code and include a payload of errors.
• If the validation passes, the endpoint should respond with a 200 status code.

Acceptance Criteria:

• Endpoint /api/workflows/authors/validate is implemented and functional.
• Endpoint correctly validates records based on their type.
• Returns 400 with validation errors if validation fails.
• Returns 200 if validation is successful.
• Validation check is added for create/update operations in author workflows.
• The record editor is updated to use the new validation endpoint.
• Unit tests are written for the new endpoint to ensure proper validation behavior.

We first have to make some changes to inspire-schemas 🫠 pyyaml and urllib3 versions need to be bumped in order to use it in inspire backoffice.
They needed changes are included in: inspirehep/inspire-schemas#465

Added validation endpoint in inspirehep/backoffice#115

I think it makes sense to wait for inspirehep/inspirehep#3246, to add the validation call in record editor
