fix: EOS run asynchronous tasks (#904)

Startup retention manager for asynchronous tasks. Handle gracefully
exceptions in these tasks or the configuration for them.

Remove tasks.py as repeated tasks are now handled by the retention
manager.

When running on GitHub, only the version date file is checked. The
development tag is merely a label, so any date set during development suffices.

The test_doc is also skipped on GitHub actions.

 **Description**: This project provides a comprehensive solution for simulating and optimizing an energy system based on renewable energy sources. With a focus on photovoltaic (PV) systems, battery storage (batteries), load management (consumer requirements), heat pumps, electric vehicles, and consideration of electricity price data, this system enables forecasting and optimization of energy flow and costs over a specified period.
