Describe the bug

I upgraded all Swashbuckle.AspNetCore (3 packages) to 7.2.0 on .NET 9, and when rendering, the UI complains that the version is not set. If I copy and paste my json into Validator I can see that it does not like the version 3.0.4.

Expected behavior

3.0.4 is supported

Actual behavior

Not supported

Steps to reproduce
