[API] API response contains inconsistencies w.r.t. API specification

[apibugsreporting]

Hi, I would like to report an issue in this API.

Endpoint: POST /v2/check

Description: When making a request to this endpoint with the following parameters:

motherTongue:pt-AO
language:pt-AO
text:sibyllic

The following inconsistencies are found in the response, according to the OpenAPI specification:

• [Response body property '/matches/[item]'] Object instance has properties which are not allowed by the schema: ["contextForSureMatch";"ignoreForIncompleteSentence";"type"]

The OpenAPI specification I am referring to is available at: https://languagetool.org/http-api/languagetool-swagger.json

A test report revealing this issue is available at: http://apitesting.ddns.net/fse2022/restest/target/allure-reports/languageTool__rw_rt_custom/#behaviors/b1a8273437954620fa374b796ffaacdd/88e50107b14a88e6/

Yes, there are undocumented values in the response, that's on purpose (the doc says "any parameters or outputs not part of this documentation are internal and must not be relied on").
