Feature/bedrock embedder

[andrewghlee]

Description

This PR adds aws_bedrock embedder to embedchain and makes minor changes to the existing code such as the following:

• Use langchain-aws instead of langchain-community for aws_bedrock llm
• Use AWS_REGION or AWS_DEFAULT_REGION before defaulting to us-west-2
• Update pre-commit config file to use newer version of ruff and remove --force-excluded as it is already done in pyproject.toml
• Add isort to pre-commit config file and have pre-commit follow the same steps in make lint and make format as specified CONTRIBUTING.MD
• Remove pinned versions for packages that share dependencies with langchain-aws such as opensearch-py (pyproject.toml) and boto3 (pip install in Makefile)

@andrewghlee Hey sure, PR looks good to me. Let me fix the failing tests first and then we are good to merge this PR.

[andrewghlee]

@Dev-Khant I think one of the undone changes had the failing test resolved actually. I cherrypicked that specific file and ran make coverage and got 419 passed, 3 skipped, 21 warnings in 54.52s.
