refactor: update step callback methods to support asynchronous invocation (#4633)

* refactor: update step callback methods to support asynchronous invocation

- Replaced synchronous step callback invocations with asynchronous counterparts in the CrewAgentExecutor class.
- Introduced a new async method _ainvoke_step_callback to handle step callbacks in an async context, improving responsiveness and performance in asynchronous workflows.

* chore: bump version to 1.10.1b1 across multiple files

- Updated version strings from 1.10.1b to 1.10.1b1 in various project files including pyproject.toml and __init__.py files.
- Adjusted dependency specifications to reflect the new version in relevant templates and modules.
