Add Bio-Pype to workflow tools list in README

[ffavero]

Bio-pype is a pipeline framework oriented for bioinformatics that implements executable code snippets embedded in markdown documents, which are then chained into DAG structures through YAML configuration files.

Key features:

• Readability-first design with markdown-based snippets
• Modular architecture for easy pipeline composition and reuse
• YAML-based DAG definitions for clear workflow structure
• Support for multiple HPC schedulers (SLURM, Torque)
• Multiple language support (Python, R, bash, Perl)

Documentation: https://bio-pype.readthedocs.io

The framework has been in active development since 2016 and is used in production for cancer genomics pipelines.
