Yup: URL validation Failing for localhost

[Purus]

Describe the bug
Value http://localhost:8080/ return as a invalid url.

To Reproduce

const yup = require('yup');

const schema = yup.string().url();

const value = 'http://localhost:8080/'

console.log(`Testing '${value}'`, schema.isValidSync(value))

Expected behavior
This should return true.

Having same issue. I think it's because localhost is not handled in here https://github.com/jquense/yup/blob/master/src/string.js#L9.

I'd also like localhost to be supported.
