typo bugfixes in getting started with prompts (#651)

tl;dr: input -> word, output -> antonym, rename to dynamic_prompt
consistently

The provided code in this example doesn't run, because the keys are
`word` and `antonym`, rather than `input` and `output`.

Also, the `ExampleSelector`-based prompt is named `few_shot_prompt` when
defined and `dynamic_prompt` in the follow-up example. The former name
is less descriptive and collides with an earlier example, so I opted for
the latter.

Thanks for making a really cool library!

LangChain comes with a few example selectors that you can use. For more details on how to use them, see [Example Selectors](./examples/example_selectors.ipynb).
You can create custom example selectors that select examples based on any criteria you want. For more details on how to do this, see [Creating a custom example selector](examples/custom_example_selector.ipynb).
