Added support for new bedrock models: Sonnet 3.5 v2.0 and Haiku 3.5

[mcauthorn]

Added support for new (us-based, we don't need other regions for now) models using inference profiles.
New models:

• Haiku 3.5 and
• Sonnet 3.5 v2.0

Side note: this is my first pull request, so I'm not sure if I've done things right (e.g. I've renamed the file). At any rate, I hope this is useful to you, it's working well for us.

Important note: to test this you need to request model access in each of the regions for a given inference profile.

Hi @mcauthorn , thanks for your contribution!

Support for Claude 3.5 Sonnet v2 has already been added, see commit.

To add support for the new Claude 3.5 Haiku, adding the following lines should be sufficient:

# llm_bedrock_anthropic.py
    register(
        BedrockClaude("us.anthropic.claude-3-5-haiku-20241022-v1:0"),
        aliases=(
            "bedrock-claude-v3.5-haiku",
            "bedrock-haiku-v3.5",
            "bh-v3.5",
        ),
    )

No need to change the filename or anything in the pyproject.toml.
