Fix with_options bug when first argument is a Proc
An ArgumentError was being raised when methods were called with (proc,
options) inside a with_options block:

    def my_method(arg1, **kwargs)
      [arg1, kwargs]
    end

    # this would raise instead of merging options
    with_options(hello: "world") do
      my_method(proc {}, {fizz: "buzz"})
    end

Fixes #45183
