Improve ESCO taxonomy

Discussion

ESCO taxonomy probably uses altLabel for pattern-matching purposes. This creates barely manageable entries.

• e.g., 1

    {
      "altLabel": [
        "KDevelop 5.0.0",
        "KDevelop 4.0.0",
        "KDevelop 4.6.0",
        "KDevelop 4.7.0",
        "KDevelop"
      ],
      "label": "KDevelop",
      ...
      }

• e.g., 2

      "altLabel": [
        "diagrams of circuits",
        "elementary diagrams",
        "electrical diagrams",
        "circuit blueprints",
        "electronics schematics",
        "electrical circuit diagrams",
        "electronic schematics",
        "circuit diagrams",
        "circuit schematics"
      ],
      "description": "Read and comprehend circuit diagrams showing the connections between the devices, such as power and signal connections.",
      "label": "circuit diagrams",

Current linguistic tools (e.g., spacy, semantic search, ...) provide searching/matching tools that could avoid redundant definitions.
