Add definitions for the values present in our JSON sentences dataset

[santanavagner]

Description (Actual Behavior)

The values present in our JSON sentences file may be interpreted differently in different contexts/cultures/domains.
Hence, we should add definitions and proper citations/references to the values used in our JSON sentences file.

Expected Behavior

Our JSON sentences file should have a definition for each social value considered and a citation to the reference considered each value. This way, when retrieving the JSON file, we could also append definition for values considered.

Possible Fix

Instead of having:

{
    "positive_values":[
        {
            "label": "accountability",
            "prompts": [
                { "text": "Genera
                ...

{
    "positive_values":[
        {
            "label": "accountability",
            "definition": { "text": "[str]", "ref": [int] },
            "prompts": [
                { "text": "Genera ...
                ...

Steps to Reproduce

NA.

Context

Improvement of taxonomy considered in the JSON sentences file and, consequently, the recommendation endpoint.
