[Go] properly set header parameters on api clients (!14586) · Merge requests · OpenAPI Tools / openapi-generator

Created by: sokolikp

This PR addresses https://github.com/OpenAPITools/openapi-generator/issues/14578. Request headers were being improperly added as query params for Go clients. This PR:

Updates the name of the function parameterAddToQuery (added in https://github.com/OpenAPITools/openapi-generator/pull/13909) to parameterAddToHeaderOrQuery to indicate that a header or query interface arg can be passed
Correctly passes localVarHeaderParams (instead of localVarQueryParams) to the above function for header params
Regenerates Go samples based on the above. Note that there are some automatic formatting/indentation changes to the samples - I can update those if necessary.
