Invalid `operationRef` in links example

[tfesenko]

OperationRef Examples suggests a value with a missing / separator after the paths in operationRef:
'#/paths~12.0~1repositories~1/{username}/get' , but it should be '#/paths/~12.0~1repositories~1/{username}/get' == '#/paths/<'/2.0/repositories/{username}'.encode()>/get.

The example of an absolute operationRef correctly uses a JSON Pointer with a /paths/<JSON Pointer-encoded path item>.

Sure! I created PR #1293 for this. Just did not know if you wanted to include this fix into the release.

Thanks, I'll review in just a few minutes. Anything that can be fixed before the actual release is welcome. This means we'll have less patch releases which is always a good thing.

Closed as fixed, thanks again!
