malformed YAML structure for endpoints about oasdiff

[reuvenharrison]

Got it.
So let's support exclude endpoints and then we can also output json.

Hi @peruzzof,
Please see: #94 and let me know if it solves the problem.

Hi @reuvenharrison, thanks again for your effort. I understood the point but, in my use case, I have two different options right now:

1. Forget the "yq" tool and create a custom script to be able to handle the yaml format
2. Create an external script to get the YAML, remove the entire "endpoints" section and keep using yq (or jq)
3. Wait for yq to properly handle this feature (mikefarah/yq#1559)

As none looks very interesting I took a look and seems feasible to add the -exclude-endpoints flag, similar to exclude-examples that already exist. I was able to create the core of it (using the existing code as an example), if I submit a PR could you review it?
Please keep in mind that I have almost no experience with Go, so it will require more effort from your side then a regular suggestion.
