fix(pipelines-components): improve title casing in AutoML and AutoRAG component README's

[mateusz-szewczyk-dev]

Description of your changes:

Summary

• Replaced the hardcoded acronym list in format_title() with a SPECIAL_CASE_WORDS mapping in constants.py, adding support for AutoML and AutoRAG alongside the existing KFP, API, URL, ID, UI, CI, CD cases.
• Moved wrap_text() from content_generator.py to utils.py and removed the leftover duplicate definition that remained in content_generator.py after the move; it now imports wrap_text() from utils.py alongside format_title().
• Minor formatting fixes: normalized spacing around an operator in yoda_data_processor/component.py and unwrapped a warning message onto a single line in validate_examples.py.

Why

wrap_text() is a general text-formatting helper, not README-content-generation logic, so it belongs in utils.py alongside format_title() rather than in content_generator.py. Completing the move (removing the stray duplicate) keeps a single source of truth. Moving the special-case word list to constants.py also makes it easier to extend without touching function logic.
