Update to NLP Sandbox schemas 1.2.0

[github-actions]

A new version of the NLP Sandbox schemas is available. Follow
these instructions to update your NLP Sandbox tool before checking
its performance on NLPSandbox.io.

1. Checkout the branch behind this Pull Request.

   git checkout <branch_name>

2. Re-run the same openapi-generator command you used to generate
   the tool stub. If you started from an existing tool
   implementation like the one included in this GitHub repository,
   run the following command to update your tool to the latest
   version of the NLP Sandbox schemas (this command would be
   defined in package.json).

   npm run generate:server:latest

3. Review the updates made to this tool in the NLP Sandbox schemas
   CHANGELOG.

4. Review and merge the changes. If you are using VS Code, this step
   can be performed relatively easily using the section named
   "Source Control". This section lists the files that have been
   modified by the generator. When clicking on a file, VS Code shows
   side-by-side the current and updated version of the file. Changes
   can be accepted or rejected at the level of an entire file or for
   a selection of lines.

5. Submit your updated tool to NLPSandbox.io.
