Integrated Swagger UI throws error on valid OpenAPI spec file

Summary

When opening a valid OpenAPI JSON file from the Repository / Files section, an error message is displayed saying:

Unable to render this definition

The provided definition does not specify a valid version field.

Please indicate a valid Swagger or OpenAPI version field. Supported version fields are swagger: "2.0" and those that match openapi: 3.0.n (for example, openapi: 3.0.0).

This problem did not occur yesterday (2022-10-26), but it does today on all our projects.

Steps to reproduce

Create a new project
Create a new file named openapi.json with the contents shown below and commit it
Open the new file from the Repository / Files section of the GitLab website

The file contents to use:
