Fix #1484

Purpose

• Fix miss counting bug: Add the untracked categories into its parent node index.yml label list.
• Fix mixed counting bug: Change the 'Tech-N' label to match the default template: increase N from root node to leaf node based on depth.

Changes

Notes: *.yml files mentioned below do not including index.yml.

• Fix miss counting bug in :technology`:

  • Add missing index.yml: `:technology/ai/generative_ai/infrastructure/index.yml .
  • Add 3rd depth :technology/ai/generative_ai/infrastructure/*.yml into :technology/ai/generative_ai/infrastructure/index.yml label list;
  • Add 3rd depth :technology/ai/generative_ai/application/*.yml into :technology/ai/generative_ai/application/index.yml label list.
  • Add 3rd depth :technology/ai/generative_ai/model/*.yml into :technology/ai/generative_ai/model/index.yml label list.
  • Add 3rd depth :technology/ai/generative_ai/tool/*.yml into :technology/ai/generative_ai/tool/index.yml label list.

• Fix mixed counting bug in :technology:

  • Change 3rd depth leaf files :technology/ai/generative_ai/*/*.yml type to Tech-3
  • Change 3rd depth leaf files :technology/ai/generative_ai/*/index.yml type to Tech-2 to represent the categories in 2rd depth directories :technology/ai/generative_ai/*/
  • Change 2nd depth leaf files :technology/ai/large_language_model/index.yml type to Tech-1 to represent the categories in 1st depth directories :technology/ai/large_language_model/.
  • Add supported label type Tech-3 into label_data_utils.ts.

Default Settings

Current depth defination: The sub-directories :technology/* in [:technology](https://github.com/X-lab2017/open-digger/tree/master/labeled_data/technology) is 0th layer, and its label type is in the :technology/*/index.yml under it with the format type: Tech-0. The type level of subordinate files increases gradually by depth.

I add some review comments about the label names and sub label which could also be applied to all other labels, can you modify the names and the labels.
