[BUG] When Response is a string(not valid JSON), `json` method occurs error

[Minsu Kim]

• Example

const instance = ky.create({});

// URL returns string 'OK'
instance.get(URL).text();

• Error Message

VM21639:1 Uncaught (in promise) SyntaxError: Unexpected token 'O', "OK" is not valid JSON

Same as when useJSON.parse('OK')

• How to solve

https://github.com/sindresorhus/ky/blob/main/source/core/Ky.ts#L81

A try-catch block may be needed when the type is json.
Now, it seems that the code has been written to ensure that the API response value is JSON.
If an error occurs while call json method, it would be good to return empty object.

• Temporary solution

instance.get(URL, { parseJson: (text) => text }).text();
