fix: version fixes, import path fixes

[Ragini-Microsoft]

Purpose

This pull request includes updates to improve dependency management and refactor imports across multiple scripts. The key changes involve standardizing the import paths for get_azure_credential and updating the versions of several dependencies in the requirements.txt files.

Import Refactoring:

• Updated the import path for get_azure_credential in the following files to use the direct module path instead of the relative path:
  • infra/scripts/aihub_scripts/create_ai_hub.py
  • infra/scripts/fabric_scripts/create_fabric_items.py
  • infra/scripts/index_scripts/create_articles_index.py
  • infra/scripts/index_scripts/create_drafts_index.py
  • infra/scripts/index_scripts/create_grants_index.py

Dependency Updates:

• Updated dependency versions in requirements.txt files to ensure compatibility and stability:
  • infra/scripts/aihub_scripts/requirements.txt: Downgraded msal to version 1.31.1.
  • infra/scripts/fabric_scripts/requirements.txt: Downgraded msal to 1.24.0, added pinned versions for azure-identity and pandas.
  • infra/scripts/index_scripts/requirements.txt: Added pinned versions for azure-storage-file-datalake, openai, pypdf, azure-identity, azure-ai-textanalytics, azure-keyvault-secrets, and pandas.
