Feat/extract notebook metadata

[firzaariany]

Summary

This PR contributes to #32 and is ready for review

What's changed

• Notebook metadata convention

  • Modifies templates/: provide dict for metadata, set tagged cells preview_image and notebook_metadata
  • Modifies notebooks/sentinel/sentinel-2/fire_and_disaster_monitoring/fire_boundary.ipynb: as a working example with metadata dict

• Record generator and image extraction

  • Adds algorithm_registration/populate_record.py: Python CLI to produce thumbnail and preview pictures, and to create OGC API records from tagged cells
  • Adds algorithm_registration/records_template.json: OGC API record template

How to test this

• Since the UDP and records were committed, it will appear in your local repo. Delete them to test this pipeline
• Run the notebook fire_boundary.ipynb from top to bottom
• Notebook will produce UDP, thumbnail & preview pictures, and OGC API records in this directory structure:

openeo-udp/algorithm_registration/fire_boundary/
├── openeo_udp/fire_boundary.json
└── records/
    ├── fire_boundary.json
    ├── preview.png
    └── thumbnail.png

• If you want to run the QA test
  • Clone developmentseed/apex_algorithms repo
  • Move the records to APEx repo

cd apex_algorithms
git checkout -b alg/fire_boundary
cp -r ../algorithm_registration/fire_boundary algorithm_catalog/developmentseed

• Run QA test locally

uv pip install qa/tools -r qa/unittests/requirements.txt
uv run pytest qa/unittests/tests/test_records.py

Problems

When running QA tests I received this error for fire_boundary records. It checks if the records exist in the main branch of ESA-APEx/apex_algorithms, which wouldn't be if the commit with fire_boundary records are not yet merged to main.

AssertionError: Link 'https://raw.githubusercontent.com/ESA-APEx/apex_algorithms/refs/heads/main/algorithm_catalog/developmentseed/fire_boundary/openeo_udp/fire_boundary.json' in record 'fire_boundary' is not returning a valid response (200, 301, 302, 308, 401, 403), got 404
