Update SDK to match the return of /users/search

[zeripath]

As per issue go-gitea/gitea#4841. The current implementation of the /users/search API does not return a UserList but rather an object similar to the SearchResults object returned by /repos/search. This pull request fixes swagger API so that it actually describes the reality of what is returned.

The issue is that this API has been wrong for at least 10 months - therefore tools may have grown up using the incorrect API. I have also created a pull request for the opposite solution go-gitea/gitea#4846 - which if pulled would mean this request was unnecessary.

I don't know what's the different between the changes?

[zeripath]

OK, so if you look at the pull-request go-gitea/gitea#4847 - the changes there make a formal UserSearchResults object which means that these changes are needed on the SDK. (This is to fix go-gitea/gitea#4841.)

(There is a way to change to go-gitea/gitea#4847 such that the SDK doesn't need to change - but this involves describing the result of /users/search in the comment rather than extracting out to a separate object.)

The alternative is to change gitea to return a UserList instead and those fixes are on #120 & go-gitea/gitea#4846

Is this still needed?

[zeripath]

Hmm. I think the swagger description is still a little special for very users list.

Needed is perhaps a strong word though.

Let me have another look.
