[Bug] Incorrect data label 'Tech-N' and labels list in labeled_data/technology and labeled_data/application_domain

[birdflyi]

Current Behavior

In label_data:
Some categories, e.g. infrastructure, are not included in the label of labeled_data/technology/ai/generative_ai/index.yml file, which will cause miss counting when calculating the overall database open source data;
Some leaf node yml files, e.g. labeled_data/technology/ai/generative_ai/application/audio.yml, has the same label level with its parent level file labeled_data/technology/ai/generative_ai/application/index.yml file, which will cause mixed counting when calculating the overall database open source data.

Expected Behavior

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

Any Additional Comments?
