this will avoid randomization in the output file

This PR looks similar to #3476.
While it reduces the entropy in the generated specification, it doesn't cover all cases.
For example elements in a list (such as enums) aren't sorted and will still depend on various other factors.

Also ref:

• [1.5.18] Swagger file rendering - Elements sorted alphabetically  #2775
• sort methods to make api generations reproducible #3266
• Swagger-Models: Make definitions use a sorted Map instead of HashMap #2400

It would be very good to at least start with deterministic output somewhere, like this PR. Enums and other 'listed' items can come later. This PR can also be extended for enums and other 'listed' items in the specification.
