add CI action to create `ahb.db` from .json files in MR AHB repo

[hf-kklein]

based on Hochfrequenz/kohlrahbi#557

where ahb.db is a sqlite db:

• pip install kohlrahbi[sqlmodels]>=1.13.0
• loop over all .json files in this repository
• upload the ahb.db as action or release artifact to github

from kohlrahbi.models.sqlmodels.anwendungshandbuch import AhbLine, AhbMetaInformation, FlatAnwendungshandbuch
from sqlmodel import Session, SQLModel, create_engine

def load_machine_readable_json_ahbs_to_db(session: Session) -> None:
    for json_path in mr_ahb_repository_root.rglob("FV*/**/*.json"):
        with open(json_path, "r", encoding="utf-8") as json_file:
            file_body = json.loads(json_file.read())
            flat_ahb = FlatAnwendungshandbuch.model_validate(file_body)
            edifact_format = EdifactFormat(json_path.parent.parent.name)  # e.g. 'COMDIS'
            edifact_format_version = EdifactFormatVersion(json_path.parent.parent.parent.name)
            file_body["meta"]["edifact_format"] = str(edifact_format)
            file_body["meta"]["edifact_format_version"] = str(edifact_format_version)
            meta = AhbMetaInformation.model_validate(file_body["meta"])
            session.add(meta)
            flat_ahb.meta = meta
            for line_index, raw_line in enumerate(file_body["lines"]):
                raw_line["position_inside_ahb"] = line_index
                line = AhbLine.model_validate(raw_line)
                flat_ahb.lines.append(line)
                session.add(line)
            session.add(flat_ahb)
            session.commit()
    session.flush()

if __name__ == '__main__':
  engine = create_engine(f"sqlite:///ahb.db")
  SQLModel.metadata.drop_all(engine)
  SQLModel.metadata.create_all(engine)
  with Session(bind=engine) as session:
     load_machine_readable_json_ahbs_to_db(session)
   # tada!

wenn wir für ahbesser direkt auf die xml-files umsteigen, wäre das vorgehen folgendes: Hochfrequenz/xml-fundamend-python#111
