Support line wrap or fixed width in generated code snippet string

Hi, is there any plans to support a fixed width or line break for the generated string from `HTTPSnippet.convert`?

While generating the string, in certain use cases, the output string could be quite long for some lines, and seems like there is no options to have line break or line wrap.

For example, the following code snippet would be hard to view since it takes too much horizontal width (the `url` field):
```
import axios from 'axios';

const options = {
method: 'POST',
url: 'https://url.com/this_is_a_super_long_url_this_is_a_super_long_url_this_is_a_super_long_url_this_is_a_super_long_url_'
};

try {
const { data } = await axios.request(options);
console.log(data);
} catch (error) {
console.error(error);
}
```

If we could possibly add a line break (boolean, or width as a number) as an option:
```
import axios from 'axios';

const options = {
method: 'POST',
url: 'https://url.com/this_is_a_super_long_url
_this_is_a_super_long_url_this_is_a_sup
er_long_url_this_is_a_super_long_url_'
};

try {
const { data } = await axios.request(options);
console.log(data);
} catch (error) {
console.error(error);
}
```

Start at the HTTPSnippet.convert entry point and trace how generated code strings are assembled for the affected targets. Define how a boolean or width option should wrap long values without changing other output, then verify the generated snippet matches the requested formatting example.
