enumerate builtin: start parameter can only be passed as positional argument, not keyword argument

[severinh]

Minimal reproducible example:

from pydantic_monty import Monty

print(Monty("enumerate(['a', 'b', 'c'], 1)").run())
# Works.
# Output: [(1, 'a'), (2, 'b'), (3, 'c')]

print(Monty("enumerate(['a', 'b', 'c'], start=1)").run())
# Does not work.
# Output: pydantic_monty.MontyRuntimeError: TypeError: enumerate expected at most 2 arguments, got 1
# Expected output (CPython): [(1, 'a'), (2, 'b'), (3, 'c')]

Fixed on main. Both enumerate(['a', 'b', 'c'], 1) and enumerate(['a', 'b', 'c'], start=1) now give [(1, 'a'), (2, 'b'), (3, 'c')], matching CPython; enumerate(iterable=['a', 'b'], start=2) also works and gives [(2, 'a'), (3, 'b')].

enumerate now goes through the FromArgs binder, and the keyword-argument error cases are covered in crates/monty/test_cases/args__macro_errors.py. Closing as fixed.
