Update RWTHDBIS training workflows

[Kleinpenny]

Summary

• Add train-method selection for RWTHDBIS term typing and taxonomy discovery, including DS-CL pretraining flow and context/no-context fine-tuning paths.
• Update RWTHDBISLearner examples to expose train_method with explanations and limit inputs for quick runs.
• Update RWTHDBIS learner documentation with comprehensive training method descriptions:
  • Document all training methods (DS-CL, FT-TC, SKPT) for Term Typing
  • Document training methods (DS-CL + without_context FT-TC, with_context FT-TC) for Taxonomy Discovery
  • Fix class name and import path for Taxonomy Discovery learner
  • Add context generation workflow documentation
  • Update parameter descriptions to match code implementation
  • Add training method selection guidance

Changes

• Code: Added train_method parameter support in both term typing and taxonomy discovery learners
• Examples: Updated examples to demonstrate train_method usage with limited inputs for quick testing
• Documentation: Comprehensive update to rwthdbis_learner.rst with detailed training method descriptions

Test plan

• /home/yxpeng/anaconda3/envs/ontolearner/bin/python examples/llm_learner_rwthdbis_term_typing.py
• /home/yxpeng/anaconda3/envs/ontolearner/bin/python examples/llm_learner_rwthdbis_taxonomy_discovery.py

Dear @Kleinpenny , thanks for your contribution. We will start reviewing your work shortly.

Dear @Kleinpenny , thanks for all the fixes. I am wondering whether you can confirm whether we need to make any changes to the documentation page as well to reflect the new version of your approach? Other than this, everything seems to be perfect, and the code is ready for merge.
