This pull request concludes the development of the 8 initial templates. All 8 templates have their respective devcontainer.json, devcontainer-template.json, NOTES.md and tests. All of the templates passed on the tests written.

The 8 templates added are:

• miniforge: Based on the Miniforge3 official image
• miniforge-dnd: Based on the Miniforge3 official image, with Docker in Docker installed
• python-utils: Based on the Official Python image, with a few tools (poetry, ruff, mypy, MonkeyType and bandit) installed using pipx
• python-dnd: Same as python-utils, but also have Docker in Docker
• pytorch-gpu: Based on the Pytorch from the Nvidia NGC Catalog
• tensorflow-gpu: Based on the TensorFlow from the Nvidia NGC Catalog
• local-colab: Based on the official Google Colab image
• python-kaggle: Based on the Official Python Kaggle image

This initial release will be used as a styling starting point for more templates.
