fix: task type sagemaker

[zanussbaum]

task type is now part of the request body in the sagemaker image

---

Important

Removed preprocess_texts and integrated task type validation into embed_text in sagemaker.py, with task type now part of the request body.

• Functionality:
  • Removed preprocess_texts function from sagemaker.py.
  • Integrated task type validation directly into embed_text function.
• Behavior:
  • embed_text now directly asserts valid task_type values: search_query, search_document, classification, clustering.
  • Removed text preprocessing step that prefixed texts with task type.
  • Task type is now part of the request body in embed_text.
• Misc:
  • Updated pyright version constraint in setup.py to <=pyright-1.1.377.
