Invalid weapon choice does not return easily understandable error message in body

[techcoachralph]

Summary:

When a user passes an invalid weapon choice, I want a clear error message so the user can know what their options for weapons are as opposed to an enum choice.

Expected Results:

{
    "error_message": "You entered the weapon choice of "ax". You can only choose from "ROCK, PAPER, or SCISSORS as a weapon".
}

Actual Results:

Error message doesn't clearly express how I can provide a correct request.

    "detail": [
        {
            "type": "enum",
            "loc": [
                "body",
                "choice"
            ],
            "msg": "Input should be 1, 2 or 3",
            "input": "ax",
            "ctx": {
                "expected": "1, 2 or 3"
            }
        }
    ]
}
