Fix syntax error in user-defined-functions docs (unecessarily capital…

…ized)

Why are these changes needed?

In https://microsoft.github.io/autogen/docs/topics/code-execution/user-defined-functions#provide-the-function-to-the-executor, the following code snippet (and subsequent similar ones) throws a syntax error:

code = f"""
from {LocalCommandLineCodeExecutor.FUNCTIONS_MODULE} import add_two_numbers

print(add_two_numbers(1, 2))
"""

due to FUNCTIONS_MODULE being unnecessarily capitalized.
Code being referred to:

autogen/autogen/coding/local_commandline_code_executor.py

Line 72 in 972b4ed

functions_module: str = "functions",
